The ssh-agent service allows adding multiple keys (including the ones protected with a passphrase) to a single pool of ssh keys, which can be shared across multiple projects.
The default ssh keys (
~/.ssh/id_ecdsa) are loaded into the agent automatically.
On macOS and Windows this happens when the Docksal VM is (re)started, on Linux - whenever
fin project start is used.
To start using the ssh-agent service, add the following configuration option under the
cli service in the project’s
cli: ... volumes: ... # Shared ssh-agent socket - docksal_ssh_agent:/.ssh-agent:ro ...
fin project reset cli.
fin help ssh-key for more information and usage guidelines.
$ fin help ssh-key Manage SSH keys loaded into Docksal Private SSH keys loaded into the secure docksal-ssh-agent service are accessible to all project containers. This allows containers to connect to the external SSH servers that require SSH keys without a need to copy over the key into the container every time. Default keys id_rsa/id_dsa/id_ecdsa are loaded automatically on every project start. Usage: fin ssh-key <command> [params] Commands: add [key-name] Add a private SSH key from $HOME/.ssh by file name Adds all default keys (id_rsa/id_dsa/id_ecdsa) if no file name is given. ls List SSH keys loaded in the docksal-ssh-agent rm Remove all keys from the docksal-ssh-agent new [key-name] Generate a new SSH key pair Examples: fin ssh-key add Loads all SSH keys with default names: id_rsa/id_dsa/id_ecdsa from $HOME/.ssh/ fin ssh-key server_rsa Loads the key stored in $HOME/.ssh/server_id_rsa into the agent fin ssh-key new server2_rsa Generates a new SSH key pair in ~/.ssh/server2_id_rsa
Adding SSH keys automatically whenever Docksal project is started can be done by defining special variable(s) within
$HOME/.docksal/docksal.env file. All variables should be prefixed with
SECRET_SSH_KEY_ plus the
identifier of the SSH key. After that has been done, restart your project with
fin project restart, and the keys will be added.
For example, assuming you have a private SSH key
$HOME/.ssh/acquia_key, you would define a variable:
When creating the variable use the file name within
$HOME/.ssh/ directory as the variable value. NOTE: the private key should be referenced, not the public one.
To add a key manually, run
fin ssh-key add <key_filename> and it will be manually loaded. NOTE: this key will only be
be available to the containers until the next docksal-ssh-agent restart.
