# ansible-role-docker

This role installs docker-ce (Docker Community Edition) on a Debian system. (Tested on Stretch and Buster) It also exposes the Docker socket over TCP on port 2376, using X509 TLS certificates to enable / disable access.

## Prerequisites

Ensure that the fqdn (hostname -f) of the host is resolvable through dns.

## Example playbook

```
---
- hosts:
  - hostname
  roles:
  - role: docker
```

## Copy TLS certificates

Copy /root/.docker/<fqdn> to your local home directory.

## Remotely connect to your docker host

```
echo 'export DOCKER_HOST=tcp://<hostname>:2376
export DOCKER_CERT_PATH=~/.docker/<hostname>
export DOCKER_TLS_VERIFY=1' > vars
source vars
docker info
```
