Remove the source code locally
For users who build the Docker image from source-code.
Assuming the default installation source-code path ~/fleek-network/lightning, run the command:
rm -rf ~/fleek-network/lightning
If you have a custom path, you need to change the pathname to the correct path you have selected during your custom install.
Stop the Docker service
The Fleek Network recommends systemctl to manage the services, either natively or docker. It's an interface that is easily to translate across the setups, and to communicate to the users in a common manner.
To prevent any negative impact on the node's reputation, it's advisable to wait until the end of the Epoch (~24h) before shutting down the node when opting out. The same applies to nodes that have opted-in but are currently offline.
To learn more, read the Lightning-CLI section for command opt.
Shutting down a Node after an Epoch can be tedious, given the remaining time an Epoch can take to end. Doing it prematurely, will cause reputation penalties, e.g. shutting down before the participation state change to offline. Therefore, a shutdown utility is available in the Tools menu option of get.fleek.network.
To access it, execute the command:
curl https://get.fleek.network | bash
If you have followed the recommendations, you should have the Systemd Unit Service setup.
To stop the service run the command:
sudo systemctl stop docker-lightning
Confirm the Docker service status
Check the status by:
sudo systemctl status docker-lightning
Disable the service by:
sudo systemctl disable docker-lightning
Once stop, you can run the following command to confirm it is not running. If you have used the recommended container name lightning-node the command you'd have to execute is:
You can check the Docker container isn't running by running the following command. Notice that we are assuming that your docker container name is the default lightning-node. If you have customized the name use the correct selected name:
sudo docker container inspect -f '{{.State.Running}}' lightning-node
Reload the daemon
Reload the daemon by:
sudo systemctl daemon-reload
Remove the Systemd Service Unit file
If you have followed the recommendations, you should find the Systemd Service Unit file at:
/etc/systemd/system/docker-lightning
To remove the file, run the command:
sudo rm -f /etc/systemd/system/docker-lightning
Delete the Docker image
For our example, we'll assume that the Docker image for Fleek Network is the default lightning-node. If you have created the image under a different name, change in accordance to your preference.
Delete the image by running the following command:
sudo docker rmi $(docker images | grep 'lightning-node')

Uninstall Docker
Uninstalling Docker should only be performed if you don't need in your system. If you already had Docker for some purpose, you should not have to uninstall it.
Visit the Docker official documentation site for uninstall instructions here.
Manage keys
The configuration directory of Fleek Network is in the host machine file system. This is the directory where you can find the config.toml, keystore for the public keys, amongst others.
/home/<USERNAME>/.lightning
For example, for the user lgtn the location of these files is:
/home/lgtn/.lightning
The directory can be deleted but have in mind that the keystore is located here. If you need to backup the keystore, be careful as this is not possible to recover by anyone. The keys are your responsibility.
To learn more about the keystore read the guide managing the keystore.
If you are happy to delete the directory, run the following command by replacing the <USERNAME> by yours:
rm -rf /home/<USERNAME>/.lightning
Remove the logs
The Docker container generates output to stdout and stderr. All the content is stored in the location:
/var/log/lightning
To completely remove the directory run the command:
sudo rm -rf /var/log/lightning
