I had to do some extra stuff for my containers, here's some info from a tutorial I wrote:

Following the Arch wiki:

# Dependencies `yay -S podman slirp4netns aardvark-dns`

# Setup podman-compose and the venv ``` python -m venv .venv source .venv/bin/activate pip3 install --user podman-compose ```

On WSL, you'll need to be on Debian bookworm or newer. Older versions of podman-compose for, ie, bullseye, do not work.

# Reserving alternate UIDs/GIDs `# usermod --add-subuids 100000-165535 --add-subgids 100000-165535 username`

# Setup the storage configuration to overlay Create/edit the following file: `vim ~/.config/containers/storage.conf`

Add/edit the following line: ``` [storage] driver="overlay" ```

# Propagate changes to podman `$ podman system migrate`

# Bring the systems up `podman-compose up`

# I'm on WSL and it's not working (DNS issues)

Check if the network created by podman has dns enabled:

``` % podman network inspect $containername_default | grep dns "dns_enabled": true, ```

If it's false, install another dns resolver:

``` sudo apt install golang-github-containernetworking-plugin-dnsname ```

Then delete the network created by podman-compose:

`podman network rm $containername_default`

## Out of memory when running `podman-compose up`

This error may include "could not map anonymous shared memory".

If you're on a mac, try increasing the amount of memory the VM can use, eg:

``` podman machine stop podman machine set --memory 4096 podman machine start ```

This will provide podman with 4GB of memory to work with when spawning containers.
