Container

This project contains my personal docker compose configurations.

Operating principle:

Changes in this repo get pushed to a bare repo on dmeiburg.de. Whenever a push is received a post-receive hook runs.

The post-receive hook then:

• deploys the code into a working directory
• decrypts .env.gpg files
• restarts stacks with changed compose files

The env files are encrypted for key@dmeiburg.de and server@dmeiburg.de.

Server setup

# create bare repo on dmeiburg.de
mkdir -p git/container.git
cd git/container.git
git init --bare

# install the post receive hook, by using this command on the local machine
# whenever the hook is edited, this command has to be used again
scp post-receive dmeiburg:~/git/container/hooks/

Local setup

# add bare repo as remote on local machine
git remote add dmeiburg ssh://root@dmeiburg.de:/root/git/container.git

Encrypting .env files

To encrypt an .env files, the following command is used:

$ gpg -er key@dmeiburg.de -r server@dmeiburg.de .env

Deployment

git push dmeiburg

If necessary the post-receive hook has to be updated via scp.
