Portainer¶

docker compose files / stacks¶

Are all here

Use one .env file and Link to it¶

its very simple just do it like this

version: '3' # (1)!
env_file:
  - /path/to/your/.env

services:
  your_service:
    image: your_image
    environment:
      - DB_PASSWORD=${DB_PASSWORD}
    # other service configurations

it needs at least version 3

and then make your .env file look something like this:

DB_PASSWORD=KJBIWUJBdwihdbuazowdgh786287z9bidjhqb8hq27hp298h28d

Tip

Like this you can create one big .env file, save it somewhere accesible (in my case the folder where I keep all my docker stuff) and then you can link all your containers to it

Update Portainer Community Edition¶

Stop and remove your existing Portainer instance. This will not affect your other Docker containers.

sudo docker stop portainer && sudo docker rm portainer

Pull the latest Portainer-CE image.

docker pull portainer/portainer-ce:latest

Deploy the new Portainer container.

docker run -d -p 9000:9000 -p 8000:8000 --name portainer --restart always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:latest

Warning

You may need to run these commands as root/sudo if you're not logged in as root.
