Running Docker in the Cloud

There are multiple ways of running docker in the cloud. This list is in order of management (cloud managed at the top)

	Service	Control plane	Data plane	multiple containers per host	Installation	Cost

Docker under a Cloud Managed Kubernetes service on Managed VM infrastructure	EKS Fargate	Managed	Managed	serverless	Managed	$144 US/month for control plane + EC2 cost
Docker under a Cloud Managed Kubernetes service on client managed VM infrastructure	EKS EC2	managed	unmanaged	yes		EC2 cost
Docker under a Cloud Managed Docker service on Managed VM Infrastructure	ECS Fargate	managed	managed	serverless
Docker on ECS on EC2 instances (in a Auto Scaling Group)	ECS EC2	managed	unmanaged	yes		EC2 cost + NLB
Docker on Elastic Beanstalk	Elastic Beanstalk	managed	unmanaged	no
RKE Rancher Kubernetes Engine	EC2	unmanaged	unmanaged	yes	RKE
Docker on single EC2s	EC2	unmanaged	unmanaged	yes	manual

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-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
