====== Docker-Compose ======

ISt kaputt, hiermit gehts aber: https://dev.to/elalemanyo/how-to-install-docker-and-docker-compose-on-raspberry-pi-1mo

Automatisiert dann den Start von dem Kram.

<code>apt-get install curl</code>
<code>sudo apt-get install curl</code>

<code>sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose</code>
<code>curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose</code>

<code>sudo chmod +x /usr/local/bin/docker-compose</code>
<code>chmod +x /usr/local/bin/docker-compose</code>

<code>sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose</code>
<code>ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose</code>

<code>sudo docker-compose --version</code>
<code>docker-compose --version</code>

<code>apt-get install docker.io</code>
<code>sudo apt-get install docker.io</code>

===== Docker Autostart =====
https://stackoverflow.com/questions/43671482/how-to-run-docker-compose-up-d-at-system-start-up

1. Script anlegen unter:
<code> cd /etc/systemd/system</code> <code>nano docker-compose-app.service</code>

2. Script:
<code># /etc/systemd/system/docker-compose-app.service

[Unit]
Description=Docker Compose Application Service
Requires=docker.service
After=docker.service

[Service]
Type=oneshot
RemainAfterExit=yes
WorkingDirectory=/root/
ExecStart=/usr/local/bin/docker-compose up -d
ExecStop=/usr/local/bin/docker-compose down
TimeoutStartSec=0

[Install]
WantedBy=multi-user.target</code>

3. Service starten (und im Proxmox auch die VM auf Boot an Start anhaben!)
<code>systemctl enable docker-compose-app</code>

4. Service starten
<code>systemctl start docker-compose-app</code>

Speicherplatz sparen z.b. wlanguru
<code>docker system prune --all --volumes --force</code>
<code>docker system prune -a -f</code>
Hat mal eben 6 GB frei geräumt ....

mit folgendem Erweiterung in Docker Compose wird das Logging eingeschränkt:
<code>
logging:
      options:
        max-size: "10m"
        max-file: "5"
</code>

===== Script =====
<code>nano docker.sh</code>
<code>
#!/bin/bash
apt-get update
apt-get upgrade -y
apt-get dist-upgrade -y
apt-get install curl vnstat iftop htop mc wget -y
curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
docker-compose --version
apt-get install docker.io -y
apt-get autoremove -y
apt-get autoclean -y
</code>
<code>chmod +x docker.sh</code>
<code>./docker.sh</code>
