Example run MongoDB

 podman run \ 
   --detach \ 
   --publish 27017:27017 \
   --userns=keep-id \ 
   --volume ./mongo-data:/data/db \

   mongo:4.4.13 
 
 # --detach, -d - Detached mode: run the container in the background and print the new container ID. The default is false
 # --publish, -p - Publish a container’s port, or range of ports, to the host.
 # --userns - Because podman runs rootless we need to assign a user that can access the local volumn.  This sets the podman user to the same user who ran the podman command.
 # --volume, -v - Create a bind mount.
 # --name - Assign a name to the container.

Example running with pods This is a test to see how apps can talk between each other in a podman network within a pod.

Create the pod

 podman pod create --userns=keep-id --publish 8080:8080 --name mypod

 podman run --detach --volume ./mongo-data:/data/db --pod mypod --name some-mongo mongo:4.4.13

 podman run -it --pod mypod --name myapp --volume ./config:/config e4ea21376d55
