How to Setup Docker Engine Containers on Linux in Azure/AWS/GCP
To run the Docker Engine on Linux in Azure, AWS or GCP, the best way is to install the Docker Engine Community image from the marketplace. It comes preinstalled with Docker Engine Community and is fully configured as per the requirements to run Docker in the cloud. Click on the links below to deploy into your environments
Getting Started with Docker
Once your Docker community server has been deployed, the following links explain how to connect to a Linux VM:
- How to connect to a Linux VM on Azure
- How to connect to a Linux VM on AWS
- How to connect to a Linux VM on GCP
Once connected and logged in, the following section explains how to start using Docker
Test Docker Engine
To verify that Docker Engine is working correctly, type the following command
sudo docker run hello-world
This command downloads a test image and runs it in a container. When the container runs, it prints an informational message and exits as per the following screenshot:
If you receive a message ‘Cannot connect to the Docker daemon‘, means that you will need to start the Docker service. Run the following command:
sudo systemctl start docker
Or
sudo service docker start
Then re run the command to verify Docker is running
sudo docker run hello-world
Running Docker and creating containers
You should now be ready to start using Docker and creating container images.
Docker Engine is installed and running. The docker group is created but no users are added to it. You need to use sudo to run Docker commands.
To manage Docker as a non-root user refer to the following documentation – https://docs.docker.com/engine/install/linux-postinstall/
Firewall Ports
If you require to open any ports in your cloud environment, The links below explain how to modify / create firewall rules depending on which cloud platform you are using.
To setup AWS firewall rules refer to – AWS Security Groups
To setup Azure firewall rules refer to – Azure Network Security Groups
To setup Google GCP firewall rules refer to – Creating GCP Firewalls
