Pre-requisites for Docker Labs

Install Docker

With the introduction of Hyper-V, this gave way for Docker Desktop for Windows which under the hood, uses WSL2's to launch a VM as the host Linux operating system.

NOTE: Running containers on Windows machines is suited for local development purposes only and is NOT RECOMMENDED FOR PRODUCTION USE.

• Install Docker on WSL2 without Docker Desktop

• Install Docker on RHEL/CentOS

• Install Docker on Ubuntu

• Install Docker on Ubuntu using Terraform

Install Docker Compose

If you're using Ubuntu, you can install docker-compose by simply running the two commands below:

$ sudo apt-get update 
$ sudo apt-get install -y docker-compose 

Read more about it in Install Docker Compose CLI plugin page.

Error: Cannot connect to the Docker daemon

In case you encounter this message when you test Docker for the first time:

docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

To resolve this, start the docker service and docker daemon,

sudo systemctl start docker
sudo systemctl enable docker
sudo systemctl status docker

sudo dockerd
