Droxy

create commands that proxy to docker

The idea

This tool helps you in creating variants of commands that proxy execution into docker containers.

Getting started

Download
To get started you either download a precompiled binary from releases.
If you would like to build the tool from source code, read the contribution part of this document.

Wiki
Take a look at the wiki examples to learn how to setup up custom commands
https://github.com/Oppodelldog/droxy/wiki

Configuration

In the config file, you define the commands you want to create.
The config file must be named droxy.toml.

The following example contains all possible configuration options, you can leave out the most of them.

droxy.toml

    Version="1"

    [[command]]
      name = "basic command"  # name of the command
      isTemplate = true       # this command can be used as a template, no command will be created
      addGroups = true        # add current systems groups  (linux only)
      impersonate = true      # use executing user and group for execution in the container (linux only)
      workDir = "/app"        # define working directory
      removeContainer=true    # remove container after command has finished
      isInteractive=true      # enable interaction with the called command
      isDetached=false          # starts the container in background
      RequireEnvVars=false    # if true, not defined env vars that are configured will lead to an error
      uniqueNames=true

      # volume mappings
      volumes = [
          "${HOME}:${HOME}",
          "${SSH_AUTH_SOCK}:/run/ssh.sock",
          "/etc/passwd:/etc/passwd:ro",
          "/etc/group:/etc/group:ro",
          "/run/docker.sock:/run/docker.sock"
      ]

      # environment variable mappings
      envvars = [
          "HOME=${HOME}",
          "SSH_AUTH_SOCK=/run/ssh.sock",
          "DOCKER_HOST=unix:///run/docker.sock"
      ]

      links = [
        "containerXY:aliasXY"
      ]

      ports = [
        "8080:80"
      ]

      portsFromParams = [
          "some regex where the group (\\d*) parses the port from",
      ]

    [[command]]
        template = "basic command"  # apply settings from template 'basic command' to this command
    	name = "php"                # name of the command which is created by calling 'docker-proxy symlinks'
    	entryPoint = "php"          # basic binary to execute inside the container
    	image = "php:7.1.13"        # docker image the container is run on

    [[command]]
        template = "basic command"
    	name = "phpstorm-php-unittest-integration"
    	entryPoint = "php"
    	image = "php:7.1.13"

    	# replace  127.0.0.1 with docker ip of host
        replaceArgs = [
            [
              "-dxdebug.remote_host=127.0.0.1",
              "-dxdebug.remote_host=172.17.0.1"
            ]
        ]

        # ensure xdebug will startup and communicate
        additionalArgs = ["-dxdebug.remote_autostart=1"]

Create commands

Once you have setup your config, you want to create commands out of it. To generate the command binaries, navigate next to droxy.toml file and execute

    droxy clones

By default droxy clones will not overwrite existing files.
If you update droxy and want to update your commands as well, add flag -f which will overwrite existing files.

creation options

There are three ways to create commands,

  • clones
  • symlinks
  • hardlinks

Here are their pros and cons

subcommand pro con
clones the command knows its directory, will find config next to command takes more disk space
symlinks takes less disk space cannot determine the commands directory, you have to provide a config filepath by env var $DROXY_CONFIG
hardlinks takes less disk space and knows directory harder to maintain

How to

Clone the repository into your go folder. The path should look like this .../go/src/github.com/Oppodelldog/droxy.

There are some make recipes that help you with several tasks, type make to get a list of those.

first: setup:

make setup

This installs necessary go tools to get further jobs done and installs vendors.

Now you are ready to go.

make install

builds and installs the droxy command in $GOPATH/bin so you can directly use or test.

If you make is not available, execute the commands of the setup task manually.
Or do as I do and make use of the droxy.toml in .build and use make from the build container.

Use make fmt and make lint to clean your code.
