ssh
Ansible requires ssh to work, so if it still needs to be done, you have to configure ssh with the publickey authentication on the remote server.
$ ssh-copy-id user@server
User user have to be added to /etc/sudoers file (or be in sudo group)!
%sudo ALL=(ALL:ALL) NOPASSWD: ALL
configuration
Prepare your own hosts:
cp hosts_example hosts
playbooks
To install docker on debian:
$ ansible-playbook playbooks/docker/install-dockerd.yml
To add configured user to docker group (if required):
$ ansible-playbook playbooks/docker/user-mod.yml
Remote docker via docker api
Nowadays, the preferred way to access the remote docker instance is through the ssh protocol (at least to me); however, if, for some reason, you want to expose the docker api on the remote host, you can use the configure-systemd playbook for that.
To configure docker api on port 2375 (systemd):
$ ansible-playbook playbooks/docker/configure-systemd.yml
If you want to secure your api with certificates (port 2376, configure-systemd-tls.yml) you have to first generate certs and put them in tsl directory:
- docker.key
- docker.pem
- myCA.pem
