Using this procedure, we set up docker using the Turnkey Core LXC container (Debian Linux).

Docker LXC Container Configuration

The container is created with the following resources:

• 4 CPUs
• 4096 KB Memory
• 8 GB SSD Storage (Shared PVE-storage)
• LS Services Network

Portainer Edge Agent

We manage Docker using a single Portainer instance.

This is done via the Portainer Edge Agent. The steps to install the Portainer Edge Agent are as follows:

1. Create a new environment on the Portainer Host
   • Select and use the Portainer edge agent choice
   • BE CAREFUL TO SELECT THE PORTAINER HOST URL, NOT THE AGENT when setting up
2. Carefully copy the EDGE_ID and  the EDGE_KEY fields into the script in the next step that is used to spin up the edge agent
3. Install the Portainer Edge Agent on the  docker container as follows:

docker run -d \
-v /var/run/docker.sock:/var/run/docker.sock \
-v /var/lib/docker/volumes:/var/lib/docker/volumes \
-v /:/host \
-v portainer_agent_data:/data \
--restart always \
-e EDGE=1 \
-e EDGE_ID=<replace with id from portainer> \
-e EDGE_KEY=<replace with key from portainer> \
-e EDGE_INSECURE_POLL=1 \
--name portainer_edge_agent \
portainer/agent:latest

Mail Forwarding

More work needs to be done here. Here’s some information to help get started –

• Postfix configuration in Turnkey LXC
• Procedure to get postfix configured to support forwarding e-mail through smtp2go.
