Welcome to part 3 of the Supporting Promote series. In this series, we will tackle some common issues and questions, and provide best practices for troubleshooting. This article will step through the process of restoring the Promote web app.
The Promote web app has crashed, and users can't interact with the UI.
First, try to SSH onto the leader node (this is where the promote_app service will be):
Confirm you're the Leader node by running the following command:
docker node ls
In the results, note the * and the Leader tag are on the same line:
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS
6iscs5yrjgo1qa8ty1gk1otp7 * den-cs-cent-01 Ready Active Reachable
dzys60hss1jgcfy13qu3lbgxs den-cs-cent-02 Ready Active Leader
qx4cu0k4hnfjdppn5739doizj den-cs-cent-03 Ready Active Reachable
Now, check the status of the services by running this command:
docker service ls
The results of the command show us that there are 0 promote_app replications!
