Running Docker in GCP - Google Kubernetes Engine

Running Docker in GCP - Cloud Run

Running Docker in GCP - Virtual Machine

Note: when running a container in docker and exposing a local port - do not use the -p flag after the container name:version - place all flags like -p -d double - name before

   sudo apt install docker.io
   sudo docker ps
   sudo dpkg --configure -a
   sudo apt-get install curl
   sudo docker run --name magellan-nbi -d -p 80:8080 obrienlabs/magellan-nbi:0.0.3-ia64

Run an Ubuntu Desktop container on Docker - for nested Docker

We used this one in ONAP https://hub.docker.com/r/dorowu/ubuntu-desktop-lxde-vnc - it needs a volume - so we will likely need do dockerfile it - to save state - if you dont

 have local drive share capability from Docker Desktop. Goto http://127.0.0.1:6080/

docker run -p 6080:80 -d --name ubuntu dorowu/ubuntu-desktop-lxde-vnc
# test a file copy
docker cp pom.xml ubuntu:/root/pom.xml

# check it
docker exec -it ubuntu bash
root@6950d3be0f24:/root# ls
Desktop  pom.xml

Network Connections to Other Docker Containers on the same Host

localhost won't work inside a container - it just resolves to itself - use a network or the following URLs

in mac

docker.for.mac.localhost

in windows or both

host.docker.internal

Docker Images by Language

Java

Alpine

Tomcat

Swift

Python


Docker-compose - legacy single node minimal orchestration

Don't use docker-compose over Kubernetes for various reasons including the fact it is a minimal deprecated single-node orchstrator
But if you absolutely need it
