Docker - Install Portainer

Create a volume to host Portainer data

docker volume create portainer_data

returns

portainer_data

NOTE: Portainer requires data persistence, and as a result needs at least one storage-class available to use.

Portainer will attempt to use the default storage class during deployment.

If you do NOT have a storage class tagged as default the deployment will likely fail.

Install the Portainer Docker Image

docker run -d -p 8000:8000 -p 9443:9443 --name portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:lts

NOTE: This will run the container to pull, install and ensure it is always running.

By default, Portainer generates and uses a self-signed SSL certificate to secure port 9443.

Port 8000 is a SSH tunnel server and is used to create a secure tunnel between the agent and the Portainer instance.

Port 8000 is not required for all users of Portainer.
It is only necessary for those who plan to use the Edge compute features with Edge agents.
Edge computing refers to the ability to manage and deploy containers on remote devices or edge locations, such as on devices at the edge of a network.
Edge agents are components that run on these remote devices to communicate with Portainer and manage containers.
