CLI Docker image for Docksal

This image is focused on console tools necessary to develop LAMP stack (and other web) applications.

This image(s) is part of the Docksal image library.

Features

  • php/php-fpm (w/ xdebug), nodejs (via nvm), python (via pyenv), ruby (via rvm)
  • Framework specific tools for Drupal, Wordpress, Magento
  • Miscellaneous cli tools for day to day web development
  • Hosting provider cli tools (Acquia, Pantheon, Platform.sh)
  • Cron job scheduling
  • Custom startup script support
  • VS Code Server (VS Code in the browser)

Versions and image tag naming convention

  • Stable versions
    • php7.3-2.14, php7.3-2, php7.3 - PHP 7.3
    • php7.4-2.14, php7.4-2, php7.4, latest - PHP 7.4
  • Development versions
    • php7.3-edge - PHP 7.3
    • php7.4-edge - PHP 7.4

PHP

  • php-fpm && php-cli
  • xdebug
  • composer v1 & v2
  • drush (Drupal)
    • drush launcher with a fallback to a global drush 8
    • registry_rebuild module
    • coder-8.x + phpcs
  • drupal console launcher (Drupal)
  • wp-cli (Wordpress)
  • mg2-codegen (Magento 2)

This image uses the official php-fpm images from Docker Hub as the base. This means that PHP and all modules are installed from source. Extra modules have to be installed in the same manner (installing them with apt-get won't work).

Available PHP database drivers

  • SQLite - via sqlite3, pdo_sqlite
  • MySQL - via mysqli, mysqlnd, pdo_mysql
  • PostgreSQL - via pgsql, pdo_pgsql
  • MSSQL - via sqlsrv and pdo_sqlsrv

Using PHP Xdebug

Xdebug is disabled by default.

To enable it, run the image with XDEBUG_ENABLED=1:

cli
...
  environment:
    ...
    - XDEBUG_ENABLED=1
    ...

See docs on using Xdebug for web and cli PHP debugging.

NodeJS

  • nvm
  • node v12.18.1 (following NodeJS LTS release cycle)
  • yarn

NodeJS is installed via nvm in the docker user's profile inside the image (/home/docker/.nvm).

If you need a different version of node, use nvm to install it, e.g, nvm install 11.6.0. Then, use nvm use 11.6.0 to use it in the current session or nvm alias default 11.6.0 to use it by default.

Python

  • pyenv
  • python 3.8.3

This image comes with a system level installed Python version from upstream (Debian 9).

Additional versions can be installed via pyenv, e.g. pyenv install 3.7.0. Then, use pyenv local 3.7.0 to use it in the current session or pyenv global 3.7.0 to set is as the default.

Note: additional versions will be installed in the docker user's profile inside the image (/home/docker/.pyenv).

Ruby

  • rvm
  • ruby v2.7.1
  • gem
  • bundler

Ruby is installed via rvm in the docker user's profile inside the image (/home/docker/.rvm).

If you need a different version, use rvm to install it, e.g, rvm install 2.5.1. Then, rvm use 2.5.1 to use it in the current session or rvm --default use 2.5.1 to use it by default.

Notable console tools

  • git with git-lfs
  • curl, wget
  • zip, unzip
  • mysql, pgsql and mssql cli clients
  • imagemagick, ghostscript
  • mc, rsync
  • mhsendmail
  • cron

Hosting provider tools

Also, see the Secrets section below for more information on managing and using your hosting provider keys.

Customizing startup

To run a custom startup script anytime the cli container has started, create a startup.sh file within the .docksal/services/cli directory. Additionally, make sure that the file is executable as well so that the container does not run into issues when attempting to execute the file.

Scheduling cron jobs

Cron can be configured by making sure there is a crontab file located within .docksal/services/cli. The file should follow the standard crontab format.

Secrets and integrations

cli can read secrets from environment variables and configure the respective integrations automatically at start.

The recommended place store secrets in Docksal is the global $HOME/.docksal/docksal.env file on the host. From there, secrets are injected into the cli container's environment.

Below is the list of secrets currently supported.

SECRET_SSH_PRIVATE_KEY

Use to pass a private SSH key. The key will be stored in /home/docker/.ssh/id_rsa inside cli and will be considered by the SSH client in addition to the keys loaded in docksal-ssh-agent when establishing a SSH connection from within cli.

This is useful when you need a project stack to inherit a private SSH key that is not shared with other project stacks on the same host (e.g. in shared CI environments).

The value must be base64 encoded, i.e:

cat /path/to/some_key_rsa | base64

SECRET_ACQUIA_CLI_KEY and SECRET_ACQUIA_CLI_SECRET

Credentials used to authenticate Acquia CLI with Acquia Cloud APIv2. Stored as ACQUIA_CLI_KEY and ACQUIA_CLI_SECRET environment variables inside cli.

Acquia CLI is installed and available globally in cli as acli.

SECRET_TERMINUS_TOKEN

Credentials used to authenticate Terminus with Pantheon. Stored in /home/docker/.terminus/ inside cli.

Terminus is installed and available globally in cli as terminus.

SECRET_PLATFORMSH_CLI_TOKEN

Credentials used to authenticate with the Platform.sh CLI tool. Stored in /home/docker/.platform inside cli.

Platform CLI is installed and available globally in cli as platform.

WEB_KEEPALIVE

Sets the delay in seconds between pings of the web container during execution fin exec. Setting this variable to non zero value prevents the project from stopping in cases of long fin exec and web container inactivity. Disabled by default (set to 0).

Git configuration

When working with git from within the image, it will ask for the user.email and user.name set before you can commit. These can be passed as environment variables and will be applied at the container startup.

GIT_USER_EMAIL="git@example.com"
GIT_USER_NAME="Docksal CLI"

Coder (Visual Studio Code web IDE)

Coder is a free, open-source web IDE.

Starting with version 2.8, there is the ide flavor of the images, which comes with Coder pre-installed, e.g.:

2.11-php7.3-ide
2.11-php7.4-ide

IDE_PASSWORD

Store your preferred password in this variable if you need to password protect the IDE environment.

See docs for instructions on using Coder in Docksal.

Composer

Composer v1 and v2 are both installed in the container. v2 is set as the default version, but while not all projects may be able to work with v2 quite yet, v1 is available by setting the COMPOSER_DEFAULT_VERSION variable to 1.

Example:

services:
  cli:
    environment:
      - COMPOSER_DEFAULT_VERSION=1

The following Composer optimization packages are no longer relevant/compatible with Composer v2 and have been dropped:

To benefit from these optimizations with Composer v1, you would need to pin the image to an older version. See Docksal documentation for more details.
