Fedora Core OS post installation steps

fcos-post-installs.md

Podman sucks at this stage. Please enable docker

1. Enable docker

systemctl enable docker

2. Add yourself to docker group. Log out and log back in to take effect

usermod -aG docker valorad

3. Download docker-compose standalone

Follow the instructions on installation page

With exception that you should not copy the file to /bin, as it is not writable in FCOS.

Remeber to mark as executable with chmod +x

4. Download buildx

Follow the instructions on installation page

Copy the executable to where you can write.

Remeber to mark as executable with chmod +x

Change SE Linux policy to allow container read/write

chcon -R -t svirt_sandbox_file_t /var/workspace

Use the fish shell in SSH

1. Visit the fish AppImage release page to get the latest link

# Note: change the link
curl -L https://github.com/mliszcz/fish-shell/releases/download/fish-3.6.1-x86_64/fish-3.6.1-x86_64.AppImage --output ./fish-3.6.1-x86_64.AppImage

2. grant execution privilege

sudo chmod +x fish-3.6.1-x86_64.AppImage 

3. As of roughly FCOS 40.20240825.3.0, AppImage no longer mounts properly.

fuse: failed to exec fusermount: No such file or directory

Workaround: Extract and run.

./fish-3.6.1-x86_64.AppImage --appimage-extract
mv squashfs-root fish-3.6.1
./fish-3.6.1/AppRun

4. Update the section of the local SSH config on your computer (Not FCOS here)

The SSH config is usually located at ~/.ssh/config

Host my-fcos
  HostName my-fcos.lan
  User valorad
  Port 22
  IdentityFile /home/valorad/.ssh/my-fcos.pem
  RequestTTY yes
  RemoteCommand /path/to/appImage/AppRun/of/fish -l

5. Next time connecting to FCOS, simply type

ssh my-fcos
