+# Debugging Charmed OSM
+
+This document aims to provide the OSM community an easy way of testing and debugging OSM.
+
+Benefits:
+
+- Use upstream published images for debugging: No need to build local images anymore.
+- Easily configure modules for debugging_mode: `juju config <module> debug_mode=True debug_pubkey="ssh-rsa ..."`.
+- Debug in K8s: All pods (the debugged ones and the rest) will be running always in K8s.
+- Seemless setup: VSCode will connect through SSH to the pods.
+
+## Install OSM
+
+Download the installer:
+
+```bash
+wget http://osm-download.etsi.org/ftp/osm-10.0-ten/install_osm.sh
+chmod +x install_osm.sh
+```
+
+Install OSM from master (tag=testing-daily):
+
+```bash
+./install_osm.sh -R testing-daily -r testing --charmed
+```
+
+Install OSM from a specific tag:
+
+```bash
+./install_osm.sh -R testing-daily -r testing --charmed --tag <X.Y.Z>
+```
+
+## Debugging
+
+Once the Charmed OSM installation has finished, you can select which applications you want to run with the debug mode.
+
+- lcm: `juju config lcm debug_mode=True  debug_pubkey="ssh-rsa ..."`
+- mon: `juju config mon debug_mode=True debug_pubkey="ssh-rsa ..."`
+- nbi: `juju config nbi debug_mode=True debug_pubkey="ssh-rsa ..."`
+- ro: `juju config ro debug_mode=True debug_pubkey="ssh-rsa ..."`
+- pol: `juju config pol debug_mode=True debug_pubkey="ssh-rsa ..."`
+
+Enabling the debug_mode will put a `sleep infinity` as the entrypoint of the container. That way, we can later connect to the pod through SSH in VSCode, and run the entrypoint of the application from the debugger.
+
+### Prepare pods
+
+Preparing the pods includes setting up the ~/.ssh/config so the VSCode can easily discover which ssh hosts are available
+
+Just execute:
+
+```bash
+./prepare_pods.sh
+```
+
+> NOTE: The public key that will be used will be `$HOME/.ssh/id_rsa.pub`. If you want to use a different one, add the absolute path to it as a first argument: `./prepare_pods.sh /path/to/key.pub`.
+
+### Connect to Pods
+
+In VScode, navigate to [Remote Explorer](https://code.visualstudio.com/docs/remote/ssh#_remember-hosts-and-advanced-settings), and select the pod to which you want to connect.
+
+You should be able to see the following hosts in the Remote Explorer:
+
+- lcm
+- mon
+- nbi
+- ro
+- pol
+
+Right click on the host, and "Connect to host in a New Window".
+
+### Add workspace
+
+The `./prepare_pods.sh` script adds a workspace to the `/root` folder of each pod, with the following name: `<module>.code-workspace`.
+
+In the window of the connected host, go to `File/Open Workspace...`. Then select the `<module>.code-workspace` file.
+
+### Run and Debug
+
+Go to extensions and install the Python extension. It will be installed in the remote pod.
+
+Now we need to add a [debug configuration](https://code.visualstudio.com/docs/editor/debugging). For that, go to the Run and Debug tab, and click on `create a launch.json file`.
+
+Now you will be asked to select a folder in your workspace. Select the folder of the main component:
+
+- LCM: select osm_lcm
+- MON: select osm_mon
+- NBI: select osm_nbi
+- RO: select osm_ng_ro
+- POL: select osm_policy_module
+
+Then select `Python` as the environment. And finally, select `Module` and enter the module of the component you are going to test (LCM example: osm_lcm.lcm)
