Debugging and UI
Waypoint includes several commands to support debugging and monitoring while developing your application.
Exec into the application container
Now that you have deployed your application, you can use
waypoint exec to run
commands in the context of the most recent deployment. Typically,
waypoint exec will be used for running database migrations and debugging. However, you
can use it for any purpose.
exec command to open a shell prompt.
$ waypoint exec /bin/bash
Since you are in the deployment directory, you will observe that Waypoint automatically executes against the currently deployed application.
From within the Docker container, validate that this is the actual application by listing out the directory hosting the application's compiled files.
$ cd / && ls
You should observe an output that contains the file structure for the current deployment.
List the processes that are running in the container.
$ ps aux
exit to leave the interactive Docker session.
View Waypoint application logs
In the application's directory, run the
logs command to observe the running
logs for your deployment.
$ waypoint logs
You will observe output similar to the following. These logs are from the existing deployment.

Access the Waypoint web UI
The Waypoint server includes a web-based user interface that you can use to view builds, deployments, and releases for projects and applications.
The web UI requires authentication. Run a single command to automatically open the browser and authenticate your session. This command will work if a graphical web browser is available on the machine where the command is being run.
$ waypoint ui -authenticate
Waypoint currently uses self-signed certificates for TLS. Your web browser will require you to bypass a certificate warning to use the UI.
