# 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
|
|
```
