    a1[curl localhost:80] -.->a2[nginx container in systemd system service]

Set up a systemd system service example2.service where rootful podman is running the container image docker.io/library/nginx. Configure socket activation for TCP port 80.

The instructions are similar to Example 1.

  1. Create the file /etc/containers/systemd/example2.container with the contents 
    [Unit]
Requires=example2.socket
After=example2.socket

[Container]
Image=docker.io/library/nginx
Environment=NGINX=3;
[Install]
WantedBy=default.target
  2. Optional step for improved security: Edit the file /etc/containers/systemd/example2.container and add this line below the line [Container] 
    Network=none
    For details, see section Possibility to restrict the network in the container
  3. Create the file /etc/systemd/system/example2.socket that defines the sockets that the container should use 
    [Unit]
Description=Example 2

[Socket]
ListenStream=0.0.0.0:80

[Install]
WantedBy=sockets.target
  4. Reload the systemd configuration 
    $ sudo systemctl daemon-reload
  5. Start the socket 
    $ sudo systemctl start example2.socket
  6. Test the web server 
    $ curl -s localhost:80 | head -4
