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 v10.15.0 w/ npm v6.4.1 (following NodeJS LTS release cycle)
• yarn

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

This image comes with NodeJS v10.15.0 by default .

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 2.7.13

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 v2.6.0
• 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

• Acquia Cloud API drush commands (Acquia)
• terminus (Pantheon)
• platform (Platform.sh)

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_ACAPI_EMAIL and SECRET_ACAPI_KEY

Credentials used to authenticate with Acquia Cloud API.
Stored in /home/docker/.acquia/cloudapi.conf inside cli.

Acquia Cloud API can be used via ac-<command> group of commands in Drush.

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.

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.

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.:

2.8-php7.1-ide
2.8-php7.2-ide
2.8-php7.3-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.
