# Container
This project contains my personal docker compose configurations.
To use this configuartions the .env files have to be decrypted with
the key@dmeiburg.de key
#### 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
```sh
$ gpg -d .env.gpg > .env
# create bare repo on dmeiburg.de
mkdir -p git/container.git
cd git/container.git
git init --bare
```
To encrypt an .env file the following command is used:
```sh
# install the post receive hook
# whenever the hook is edited, this command has to be used again
scp post-receive dmeiburg:~/git/container/hooks/
```
#### Local setup
```sh
# add bare repos 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:
```sh
$ gpg -er key@dmeiburg.de -r server@dmeiburg.de .env

#### Deployment
```bash
git remote add dmeiburg ssh://root@dmeiburg.de:/root/git/container.git
git push dmeiburg
```
Make sure `post-receive` hook is installed in the bare repository.
If necessary the post-receive hook has to be updated via scp.
