Installeren docker & docker-compose

Dit is stap 1 van de serie Home-assistant & docker, van aqara tot z-wave in een stap of 10

 

Zoals gezegd starten we met een verse installatie van Ubuntu 18.04 LTS (Bionic Beaver). Niets geinstalleerd, anders dan gewoon geupdate.

 

Docker

Op de console installeren we eerste docker.op  met het commando :

sudo apt install docker.io

We kunnen testen of docker werkt door bijvoorbeeld de versie op te vragen:

lbeuker@ubuntu:~$ docker --version
Docker version 17.12.1-ce, build 7390fc6

 

Docker-Compose

 

Docker werkt prima voor het draaien van 1 of meerdere containers. Maar het is natuurlijk veel mooier om 1 pakket te maken van alle afhankelijkheden binnen 1 configuratie.
Dat is waar docker-compose om de hoek komt kijken. We maken 1 configuratie waarin we een losse container voor home-assistant, influxdb en grafana kunnen maken. Later kunnen we deze uitbreiden met mqtt.

Helaas is docker-compose nog niet via de package manager te installeren. Daarom moet je deze handmatig instlalleren via het volgende commando:

sudo curl -L https://github.com/docker/compose/releases/download/1.21.2/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose

Op dit moment is  versie 1.21.2 de laatste versie.  Kijk voor installatie even of er een nieuwe release is op  https://github.com/docker/compose/releases

Op een verse ubuntu instalaltie is curl echter niet beschikbaar, dus eerst installeren we dat.

lbeuker@ubuntu:~$ sudo apt install curl

The following additional packages will be installed:

En daarna installeren we docker-compose versie 1.21.2. 

 sudo curl -L https://github.com/docker/compose/releases/download/1.21.2/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose

% Total % Received % Xferd Average Speed Time Time Time Current
 Dload Upload Total Spent Left Speed
100 617 0 617 0 0 1058 0 --:--:-- --:--:-- --:--:-- 1056
100 10.3M 100 10.3M 0 0 2006k 0 0:00:05 0:00:05 --:--:-- 2752k

Nu de binary gedownload is in /usr/local/bin/docker-compose moet deze nog execute rechten krijgen zodat het gebruitk kan worden middels commando :

sudo chmod +x /usr/local/bin/docker-compose

Om te kijken of het werkt kunnen we de versie opvragen:

lbeuker@ubuntu:~$ docker-compose --version
docker-compose version 1.21.2, build a133471

 

Nu docker-compose is geinstalleerd kunnen we verder met het inrichten van containers.
