GIT over SSH in Ansible hangs, eventhough ssh-agent forwarding is set up

Question

I have set up everyhing I could find, but still cloning a repo from GitHub hangs the provisioning process.

I have:

• server in known_hosts

• .ssh/config

  Host github.com   ForwardAgent yes   StrictHostKeyChecking no 

• copied private key

• public key is in authorized_keys
• the command runs as vagrant user

• the play is:

  - name: Checkout from git   git: [email protected]:username/repositoryname.git dest=/srv/website 

Answer 1

Just to expand on tillda's answer, that config can be placed in an ansible.cfg file alongside your playbook. e.g.:

ansible.cfg

[defaults] transport = ssh  [ssh_connection] ssh_args = -o ForwardAgent=yes 

I'd say it's better to do that than setting as an env variable, as placing it in a conf file is both more declarative and also will minimise the steps needed for other people you may be working with to going with a project.

I want to share the answer that worked for me:

For ansible, ssh-add to load ssh keys in your host machine first. Then use "ssh" as connection type with forwarding enabled.

Such as:

$ ssh-add   $ export ANSIBLE_TRANSPORT="ssh"   $ export  ANSIBLE_SSH_ARGS="-o ForwardAgent=yes" 

See manual for ssh-add for running the agent.

The Ansible docs for ssh-args are http://docs.ansible.com/intro_configuration.html#ssh-args
