Use the Docker plugin to build and push Docker images to a registry. The following parameters are used to configure this plugin:
|
||||
Use the Docker plugin to build and push Docker images to a public or even a
|
||||
private registry.
|
||||
|
||||
* `registry` - authenticates to this registry
|
||||
* `username` - authenticates with this username
|
||||
* `password` - authenticates with this password
|
||||
* `email` - authenticates with this email
|
||||
* `repo` - repository name for the image
|
||||
* `tag` - repository tag for the image
|
||||
* `file` - dockerfile to be used, defaults to Dockerfile
|
||||
* `context` - the context path to use, defaults to root of the git repo
|
||||
* `insecure` - enable insecure communication to this registry
|
||||
* `mirror` - use a mirror registry instead of pulling images directly from the central Hub
|
||||
* `bip` - use for pass bridge ip
|
||||
* `dns` - set custom dns servers for the container
|
||||
* `storage_driver` - use `aufs`, `devicemapper`, `btrfs` or `overlay` driver
|
||||
* `storage_path` - location of docker daemon storage on disk
|
||||
* `build_args` - [build arguments](https://docs.docker.com/engine/reference/commandline/build/#set-build-time-variables-build-arg) to pass to `docker build`
|
||||
* `mtu` - custom [mtu settings](https://docs.docker.com/v1.8/articles/networking/#docker0) when starting the docker daemon
|
||||
## Config
|
||||
|
||||
The following is a sample Docker configuration in your .drone.yml file:
|
||||
The following parameters are used to configure the plugin:
|
||||
|
||||
* **registry** - authenticates to this registry
|
||||
* **username** - authenticates with this username
|
||||
* **password** - authenticates with this password
|
||||
* **email** - authenticates with this email
|
||||
* **repo** - repository name for the image
|
||||
* **tag** - repository tag for the image
|
||||
* **file** - dockerfile to be used, defaults to Dockerfile
|
||||
* **context** - the context path to use, defaults to root of the git repo
|
||||
* **insecure** - enable insecure communication to this registry
|
||||
* **mirror** - use a mirror registry instead of pulling images directly from the central Hub
|
||||
* **bip** - use for pass bridge ip
|
||||
* **dns** - set custom dns servers for the container
|
||||
* **storage_driver** - use `aufs`, `devicemapper`, `btrfs` or `overlay` driver
|
||||
* **storage_path** - location of docker daemon storage on disk
|
||||
* **build_args** - [build arguments](https://docs.docker.com/engine/reference/commandline/build/#set-build-time-variables-build-arg) to pass to `docker build`
|
||||
* **mtu** - custom [mtu settings](https://docs.docker.com/v1.8/articles/networking/#docker0) when starting the docker daemon
|
||||
|
||||
The following secret values can be set to configure the plugin.
|
||||
|
||||
* **DOCKER_REGISTRY** - corresponds to **registry**
|
||||
* **DOCKER_USERNAME** - corresponds to **username**
|
||||
* **DOCKER_PASSWORD** - corresponds to **password**
|
||||
* **DOCKER_EMAIL** - corresponds to **email**
|
||||
|
||||
It is highly recommended to put the **DOCKER_USERNAME**, **DOCKER_PASSWORD**
|
||||
and **DOCKER_EMAIL** into secrets so it is not exposed to users. This can be
|
||||
done using the drone-cli.
|
||||
|
||||
```bash
|
||||
drone secret add --image=docker \
|
||||
octocat/hello-world DOCKER_USERNAME kevinbacon
|
||||
|
||||
drone secret add --image=docker \
|
||||
octocat/hello-world DOCKER_PASSWORD pa55word
|
||||
|
||||
drone secret add --image=docker \
|
||||
octocat/hello-world DOCKER_EMAIL kevin.bacon@mail.com
|
||||
```
|
||||
|
||||
Then sign the YAML file after all secrets are added.
|
||||
|
||||
```bash
|
||||
drone sign octocat/hello-world
|
||||
```
|
||||
|
||||
See [secrets](http://readme.drone.io/0.5/usage/secrets/) for additional
|
||||
information on secrets

## Caching
|
||||
|
||||
The Drone build environment is, by default, ephemeral meaning that you layers are not saved between builds. There are two methods for caching your layers.

## Troubleshooting
|

For detailed output you can set the `DOCKER_LAUNCH_DEBUG` environment variable in your plugin configuration. This starts Docker with verbose logging enabled.

# cli.go
|
||||
|
||||
`cli.go` is simple, fast, and fun package for building command line apps in Go. The goal is to enable developers to write fast and distributable command line applications in an expressive way.
|
||||
|
||||
## Overview
|
||||
|
||||
Command line apps are usually so tiny that there is absolutely no reason why your code should *not* be self-documenting. Things like generating help text and parsing command flags/options should not hinder productivity when writing a command line app.
|
||||
|
||||
**This is where `cli.go` comes into play.** `cli.go` makes command line programming fun, organized, and expressive!
|
||||
|
||||
## Installation
|
||||
|
||||
Make sure you have a working Go environment (go 1.1+ is *required*). [See the install instructions](http://golang.org/doc/install.html).
|
||||
|
||||
To install `cli.go`, simply run:
|
||||
```
|
||||
$ go get github.com/codegangsta/cli
|
||||
```
|
||||
|
||||
Make sure your `PATH` includes to the `$GOPATH/bin` directory so your commands can be easily used:
|
||||
```
|
||||
export PATH=$PATH:$GOPATH/bin
|
||||
```
|
||||
|
||||
## Getting Started
|
||||
|
||||
One of the philosophies behind `cli.go` is that an API should be playful and full of discovery. So a `cli.go` app can be as little as one line of code in `main()`.
|
||||
|
||||
``` go
|
||||
package main
|
||||
|
||||
import (
|
||||
"os"
|
||||
"github.com/codegangsta/cli"
|
||||
)
|
||||
|
||||
func main() {
|
||||
cli.NewApp().Run(os.Args)
|
||||
}
|
||||
```
|
||||
|
||||
This app will run and show help text, but is not very useful. Let's give an action to execute and some help documentation:
|
||||
|
||||
``` go
|
||||
package main
|
||||
|
||||
import (
|
||||
"os"
|
||||
"github.com/codegangsta/cli"
|
||||
)
|
||||
|
||||
func main() {
|
||||
app := cli.NewApp()
|
||||
app.Name = "boom"
|
||||
app.Usage = "make an explosive entrance"
|
||||
app.Action = func(c *cli.Context) {
|
||||
println("boom! I say!")
|
||||
}
|
||||
|
||||
app.Run(os.Args)
|
||||
}
|
||||
```
|
||||
|
||||
Running this already gives you a ton of functionality, plus support for things like subcommands and flags, which are covered below.
|
||||
|
||||
## Example
|
||||
|
||||
Being a programmer can be a lonely job. Thankfully by the power of automation that is not the case! Let's create a greeter app to fend off our demons of loneliness!
|
||||
|
||||
Start by creating a directory named `greet`, and within it, add a file, `greet.go` with the following code in it:
|
||||
|
||||
``` go
|
||||
package main
|
||||
|
||||
import (
|
||||
"os"
|
||||
"github.com/codegangsta/cli"
|
||||
)
|
||||
|
||||
func main() {
|
||||
app := cli.NewApp()
|
||||
app.Name = "greet"
|
||||
app.Usage = "fight the loneliness!"
|
||||
app.Action = func(c *cli.Context) {
|
||||
println("Hello friend!")
|
||||
}
|
||||
|
||||
app.Run(os.Args)
|
||||
}
|
||||
```
|
||||
|
||||
Install our command to the `$GOPATH/bin` directory:
|
||||
|
||||
```
|
||||
$ go install
|
||||
```
|
||||
|
||||
Finally run our new command:
|
||||
|
||||
```
|
||||
$ greet
|
||||
Hello friend!
|
||||
```
|
||||
|
||||
`cli.go` also generates neat help text:
|
||||
|
||||
```
|
||||
$ greet help
|
||||
NAME:
|
||||
greet - fight the loneliness!
|
||||
|
||||
USAGE:
|
||||
greet [global options] command [command options] [arguments...]
|
||||
|
||||
VERSION:
|
||||
0.0.0
|
||||
|
||||
COMMANDS:
|
||||
help, h Shows a list of commands or help for one command
|
||||
|
||||
GLOBAL OPTIONS
|
||||
--version Shows version information
|
||||
```
|
||||
|
||||
### Arguments
|
||||
|
||||
You can lookup arguments by calling the `Args` function on `cli.Context`.
|
||||
|
||||
``` go
|
||||
...
|
||||
app.Action = func(c *cli.Context) {
|
||||
println("Hello", c.Args()[0])
|
||||
}
|
||||
...
|
||||
```
|
||||
|
||||
### Flags
|
||||
|
||||
Setting and querying flags is simple.
|
||||
|
||||
``` go
|
||||
...
|
||||
app.Flags = []cli.Flag {
|
||||
cli.StringFlag{
|
||||
Name: "lang",
|
||||
Value: "english",
|
||||
Usage: "language for the greeting",
|
||||
},
|
||||
}
|
||||
app.Action = func(c *cli.Context) {
|
||||
name := "someone"
|
||||
if c.NArg() > 0 {
|
||||
name = c.Args()[0]
|
||||
}
|
||||
if c.String("lang") == "spanish" {
|
||||
println("Hola", name)
|
||||
} else {
|
||||
println("Hello", name)
|
||||
}
|
||||
}
|
||||
...
|
||||
```
|
||||
|
||||
You can also set a destination variable for a flag, to which the content will be scanned.
|
||||
|
||||
``` go
|
||||
...
|
||||
var language string
|
||||
app.Flags = []cli.Flag {
|
||||
cli.StringFlag{
|
||||
Name: "lang",
|
||||
Value: "english",
|
||||
Usage: "language for the greeting",
|
||||
Destination: &language,
|
||||
},
|
||||
}
|
||||
app.Action = func(c *cli.Context) {
|
||||
name := "someone"
|
||||
if c.NArg() > 0 {
|
||||
name = c.Args()[0]
|
||||
}
|
||||
if language == "spanish" {
|
||||
println("Hola", name)
|
||||
} else {
|
||||
println("Hello", name)
|
||||
}
|
||||
}
|
||||
...
|
||||
```
|
||||
|
||||
See full list of flags at http://godoc.org/github.com/codegangsta/cli
|
||||
|
||||
#### Alternate Names
|
||||
|
||||
You can set alternate (or short) names for flags by providing a comma-delimited list for the `Name`. e.g.
|
||||
|
||||
``` go
|
||||
app.Flags = []cli.Flag {
|
||||
cli.StringFlag{
|
||||
Name: "lang, l",
|
||||
Value: "english",
|
||||
Usage: "language for the greeting",
|
||||
},
|
||||
}
|
||||
```
|
||||
|
||||
That flag can then be set with `--lang spanish` or `-l spanish`. Note that giving two different forms of the same flag in the same command invocation is an error.
|
||||
|
||||
#### Values from the Environment
|
||||
|
||||
You can also have the default value set from the environment via `EnvVar`. e.g.
|
||||
|
||||
``` go
|
||||
app.Flags = []cli.Flag {
|
||||
cli.StringFlag{
|
||||
Name: "lang, l",
|
||||
Value: "english",
|
||||
Usage: "language for the greeting",
|
||||
EnvVar: "APP_LANG",
|
||||
},
|
||||
}
|
||||
```
|
||||
|
||||
The `EnvVar` may also be given as a comma-delimited "cascade", where the first environment variable that resolves is used as the default.
|
||||
|
||||
``` go
|
||||
app.Flags = []cli.Flag {
|
||||
cli.StringFlag{
|
||||
Name: "lang, l",
|
||||
Value: "english",
|
||||
Usage: "language for the greeting",
|
||||
EnvVar: "LEGACY_COMPAT_LANG,APP_LANG,LANG",
|
||||
},
|
||||
}
|
||||
```
|
||||
|
||||
#### Values from alternate input sources (YAML and others)
|
||||
|
||||
There is a separate package altsrc that adds support for getting flag values from other input sources like YAML.
|
||||
|
||||
In order to get values for a flag from an alternate input source the following code would be added to wrap an existing cli.Flag like below:
|
||||
|
||||
``` go
|
||||
altsrc.NewIntFlag(cli.IntFlag{Name: "test"})
|
||||
```
|
||||
|
||||
Initialization must also occur for these flags. Below is an example initializing getting data from a yaml file below.
|
||||
|
||||
``` go
|
||||
command.Before = altsrc.InitInputSourceWithContext(command.Flags, NewYamlSourceFromFlagFunc("load"))
|
||||
```
|
||||
|
||||
The code above will use the "load" string as a flag name to get the file name of a yaml file from the cli.Context.
|
||||
It will then use that file name to initialize the yaml input source for any flags that are defined on that command.
|
||||
As a note the "load" flag used would also have to be defined on the command flags in order for this code snipped to work.
|
||||
|
||||
Currently only YAML files are supported but developers can add support for other input sources by implementing the
|
||||
altsrc.InputSourceContext for their given sources.
|
||||
|
||||
Here is a more complete sample of a command using YAML support:
|
||||
|
||||
``` go
|
||||
command := &cli.Command{
|
||||
Name: "test-cmd",
|
||||
Aliases: []string{"tc"},
|
||||
Usage: "this is for testing",
|
||||
Description: "testing",
|
||||
Action: func(c *cli.Context) {
|
||||
// Action to run
|
||||
},
|
||||
Flags: []cli.Flag{
|
||||
NewIntFlag(cli.IntFlag{Name: "test"}),
|
||||
cli.StringFlag{Name: "load"}},
|
||||
}
|
||||
command.Before = InitInputSourceWithContext(command.Flags, NewYamlSourceFromFlagFunc("load"))
|
||||
err := command.Run(c)
|
||||
```
|
||||
|
||||
### Subcommands
|
||||
|
||||
Subcommands can be defined for a more git-like command line app.
|
||||
|
||||
```go
|
||||
...
|
||||
app.Commands = []cli.Command{
|
||||
{
|
||||
Name: "add",
|
||||
Aliases: []string{"a"},
|
||||
Usage: "add a task to the list",
|
||||
Action: func(c *cli.Context) {
|
||||
println("added task: ", c.Args().First())
|
||||
},
|
||||
},
|
||||
{
|
||||
Name: "complete",
|
||||
Aliases: []string{"c"},
|
||||
Usage: "complete a task on the list",
|
||||
Action: func(c *cli.Context) {
|
||||
println("completed task: ", c.Args().First())
|
||||
},
|
||||
},
|
||||
{
|
||||
Name: "template",
|
||||
Aliases: []string{"r"},
|
||||
Usage: "options for task templates",
|
||||
Subcommands: []cli.Command{
|
||||
{
|
||||
Name: "add",
|
||||
Usage: "add a new template",
|
||||
Action: func(c *cli.Context) {
|
||||
println("new task template: ", c.Args().First())
|
||||
},
|
||||
},
|
||||
{
|
||||
Name: "remove",
|
||||
Usage: "remove an existing template",
|
||||
Action: func(c *cli.Context) {
|
||||
println("removed task template: ", c.Args().First())
|
||||
},
|
||||
},
|
||||
},
|
||||
},
|
||||
}
|
||||
...
|
||||
```
|
||||
|
||||
### Subcommands categories
|
||||
|
||||
For additional organization in apps that have many subcommands, you can
|
||||
associate a category for each command to group them together in the help
|
||||
output.
|
||||
|
||||
E.g.
|
||||
|
||||
```go
|
||||
...
|
||||
app.Commands = []cli.Command{
|
||||
{
|
||||
Name: "noop",
|
||||
},
|
||||
{
|
||||
Name: "add",
|
||||
Category: "template",
|
||||
},
|
||||
{
|
||||
Name: "remove",
|
||||
Category: "template",
|
||||
},
|
||||
}
|
||||
...
|
||||
```
|
||||
|
||||
Will include:
|
||||
|
||||
```
|
||||
...
|
||||
COMMANDS:
|
||||
noop
|
||||
|
||||
Template actions:
|
||||
add
|
||||
remove
|
||||
...
|
||||
```
|
||||
|
||||
### Bash Completion
|
||||
|
||||
You can enable completion commands by setting the `EnableBashCompletion`
|
||||
flag on the `App` object. By default, this setting will only auto-complete to
|
||||
show an app's subcommands, but you can write your own completion methods for
|
||||
the App or its subcommands.
|
||||
|
||||
```go
|
||||
...
|
||||
var tasks = []string{"cook", "clean", "laundry", "eat", "sleep", "code"}
|
||||
app := cli.NewApp()
|
||||
app.EnableBashCompletion = true
|
||||
app.Commands = []cli.Command{
|
||||
{
|
||||
Name: "complete",
|
||||
Aliases: []string{"c"},
|
||||
Usage: "complete a task on the list",
|
||||
Action: func(c *cli.Context) {
|
||||
println("completed task: ", c.Args().First())
|
||||
},
|
||||
BashComplete: func(c *cli.Context) {
|
||||
// This will complete if no args are passed
|
||||
if c.NArg() > 0 {
|
||||
return
|
||||
}
|
||||
for _, t := range tasks {
|
||||
fmt.Println(t)
|
||||
}
|
||||
},
|
||||
}
|
||||
}
|
||||
...
|
||||
```
|
||||
|
||||
#### To Enable
|
||||
|
||||
Source the `autocomplete/bash_autocomplete` file in your `.bashrc` file while
|
||||
setting the `PROG` variable to the name of your program:
|
||||
|
||||
`PROG=myprogram source /.../cli/autocomplete/bash_autocomplete`
|
||||
|
||||
#### To Distribute
|
||||
|
||||
Copy `autocomplete/bash_autocomplete` into `/etc/bash_completion.d/` and rename
|
||||
it to the name of the program you wish to add autocomplete support for (or
|
||||
automatically install it there if you are distributing a package). Don't forget
|
||||
to source the file to make it active in the current shell.
|
||||
|
||||
```
|
||||
sudo cp src/bash_autocomplete /etc/bash_completion.d/<myprogram>
|
||||
source /etc/bash_completion.d/<myprogram>
|
||||
```
|
||||
|
||||
Alternatively, you can just document that users should source the generic
|
||||
`autocomplete/bash_autocomplete` in their bash configuration with `$PROG` set
|
||||
to the name of their program (as above).
|
||||
|
||||
## Contribution Guidelines
|
||||
|
||||
Feel free to put up a pull request to fix a bug or maybe add a feature. I will give it a code review and make sure that it does not break backwards compatibility. If I or any other collaborators agree that it is in line with the vision of the project, we will work with you to get the code into a mergeable state and merge it into the master branch.
|
||||
|
||||
If you have contributed something significant to the project, I will most likely add you as a collaborator. As a collaborator you are given the ability to merge others pull requests. It is very important that new code does not break existing code, so be careful about what code you do choose to merge. If you have any questions feel free to link @codegangsta to the issue in question and we can review it together.
|
||||
|
||||
If you feel like you have contributed to the project but have not yet been added as a collaborator, I probably forgot to add you. Hit @codegangsta up over email and we will get it figured out.

# Change Log
|
||||
|
||||
**ATTN**: This project uses [semantic versioning](http://semver.org/).
|
||||
|
||||
## [Unreleased]
|
||||
### Added
|
||||
- Flag type code generation via `go generate`
|
||||
- Write to stderr and exit 1 if action returns non-nil error
|
||||
|
||||
### Changed
|
||||
- Raise minimum tested/supported Go version to 1.2+
|
||||
|
||||
## [1.18.0] - 2016-06-27
|
||||
### Added
|
||||
- `./runtests` test runner with coverage tracking by default
|
||||
- testing on OS X
|
||||
- testing on Windows
|
||||
- `UintFlag`, `Uint64Flag`, and `Int64Flag` types and supporting code
|
||||
|
||||
### Changed
|
||||
- Use spaces for alignment in help/usage output instead of tabs, making the
|
||||
output alignment consistent regardless of tab width
|
||||
|
||||
### Fixed
|
||||
- Printing of command aliases in help text
|
||||
- Printing of visible flags for both struct and struct pointer flags
|
||||
- Display the `help` subcommand when using `CommandCategories`
|
||||
- No longer swallows `panic`s that occur within the `Action`s themselves when
|
||||
detecting the signature of the `Action` field
|
||||
|
||||
## [1.17.0] - 2016-05-09
|
||||
### Added
|
||||
- Pluggable flag-level help text rendering via `cli.DefaultFlagStringFunc`
|
||||
- `context.GlobalBoolT` was added as an analogue to `context.GlobalBool`
|
||||
- Support for hiding commands by setting `Hidden: true` -- this will hide the
|
||||
commands in help output
|
||||
|
||||
### Changed
|
||||
- `Float64Flag`, `IntFlag`, and `DurationFlag` default values are no longer
|
||||
quoted in help text output.
|
||||
- All flag types now include `(default: {value})` strings following usage when a
|
||||
default value can be (reasonably) detected.
|
||||
- `IntSliceFlag` and `StringSliceFlag` usage strings are now more consistent
|
||||
with non-slice flag types
|
||||
- Apps now exit with a code of 3 if an unknown subcommand is specified
|
||||
(previously they printed "No help topic for...", but still exited 0. This
|
||||
makes it easier to script around apps built using `cli` since they can trust
|
||||
that a 0 exit code indicated a successful execution.
|
||||
- cleanups based on [Go Report Card
|
||||
feedback](https://goreportcard.com/report/github.com/urfave/cli)
|
||||
|
||||
## [1.16.0] - 2016-05-02
|
||||
### Added
|
||||
- `Hidden` field on all flag struct types to omit from generated help text
|
||||
|
||||
### Changed
|
||||
- `BashCompletionFlag` (`--enable-bash-completion`) is now omitted from
|
||||
generated help text via the `Hidden` field
|
||||
|
||||
### Fixed
|
||||
- handling of error values in `HandleAction` and `HandleExitCoder`
|
||||
|
||||
## [1.15.0] - 2016-04-30
|
||||
### Added
|
||||
- This file!
|
||||
- Support for placeholders in flag usage strings
|
||||
- `App.Metadata` map for arbitrary data/state management
|
||||
- `Set` and `GlobalSet` methods on `*cli.Context` for altering values after
|
||||
parsing.
|
||||
- Support for nested lookup of dot-delimited keys in structures loaded from
|
||||
YAML.
|
||||
|
||||
### Changed
|
||||
- The `App.Action` and `Command.Action` now prefer a return signature of
|
||||
`func(*cli.Context) error`, as defined by `cli.ActionFunc`. If a non-nil
|
||||
`error` is returned, there may be two outcomes:
|
||||
- If the error fulfills `cli.ExitCoder`, then `os.Exit` will be called
|
||||
automatically
|
||||
- Else the error is bubbled up and returned from `App.Run`
|
||||
- Specifying an `Action` with the legacy return signature of
|
||||
`func(*cli.Context)` will produce a deprecation message to stderr
|
||||
- Specifying an `Action` that is not a `func` type will produce a non-zero exit
|
||||
from `App.Run`
|
||||
- Specifying an `Action` func that has an invalid (input) signature will
|
||||
produce a non-zero exit from `App.Run`
|
||||
|
||||
### Deprecated
|
||||
- <a name="deprecated-cli-app-runandexitonerror"></a>
|
||||
`cli.App.RunAndExitOnError`, which should now be done by returning an error
|
||||
that fulfills `cli.ExitCoder` to `cli.App.Run`.
|
||||
- <a name="deprecated-cli-app-action-signature"></a> the legacy signature for
|
||||
`cli.App.Action` of `func(*cli.Context)`, which should now have a return
|
||||
signature of `func(*cli.Context) error`, as defined by `cli.ActionFunc`.
|
||||
|
||||
### Fixed
|
||||
- Added missing `*cli.Context.GlobalFloat64` method
|
||||
|
||||

"""
|
||||
The flag types that ship with the cli library have many things in common, and
|
||||
so we can take advantage of the `go generate` command to create much of the
|
||||
source code from a list of definitions. These definitions attempt to cover
|
||||
the parts that vary between flag types, and should evolve as needed.
|
||||
|
||||
An example of the minimum definition needed is:
|
||||
|
||||
{
|
||||
"name": "SomeType",
|
||||
"type": "sometype",
|
||||
"context_default": "nil"
|
||||
}
|
||||
|
||||
In this example, the code generated for the `cli` package will include a type
|
||||
named `SomeTypeFlag` that is expected to wrap a value of type `sometype`.
|
||||
Fetching values by name via `*cli.Context` will default to a value of `nil`.
|
||||
|
||||
A more complete, albeit somewhat redundant, example showing all available
|
||||
definition keys is:
|
