Docker composer basics

Lets make folders (Windows)

mkdir -p c:\docker\weptop
mkdir -p c:\docker\mount
mkdir -p c:\docker\traefik
mkdir -p c:\docker\logs

Mac computer only

cd ~
mkdir docker
cd docker 
mkdir weptop
mkdir mount
mkdir traefik
mkdir logs

Create a Docker composer file

Manual way

nano docker-compose.yml

OR

code docker-compose.yml

OR

Automation

cd c:\docker\traefik

Invoke-WebRequest -Uri https://raw.githubusercontent.com/TeroKeso/Traefik_2023/main/2-traefik.yml -OutFile docker-compose.yml -UseBasicParsing

MAC
curl https://raw.githubusercontent.com/TeroKeso/Traefik_2023/main/2-traefik.yml --output docker-compose.yml

Start a docker composer prosess by reading docker-compose.yml

docker-compose up -d

Let's read docker-composer log and docker prosess

docker-compose logs
docker ps
docker inspect CONTAINER_NAMEs

Docker-compose up and scale

docker-compose up -d
docker-compose up --scale whoami=2 -d
docker-compose up --scale whoami=3 -d

Docker stop and remove container

docker ps 
docker stop CONTAINERNAME / ID
docker rm CONTAINERNAME / ID

Update docker Composer image

docker-compose pull
docker-compose up -d

Clean all non used images, containers and networks

docker system prune 

Extra voluntary docker network practices. This will need to done on your own linux computer and network

You cant do this in HAMK network because you don't know network range and ALL ip are being given out with DHCP server.

How to use macvlan networks

Docker network commands

docker network ls
docker network create -d macvlan-subnet 192.168.0.0/24 -gateway 192.168.0.1 -ip-range 192.168.0.253/32 -o parent=eth0 custommacvlannetworkwemade
