Bug

[BUG] Cannot connect to a postgres database hosted on Amazon AWS on the “Add Data Sources” page. “Test Connection” keeps running for a while but never changes to “Add Data Source”. I have tested with a publicly available postgres database, with the details given in the chaos-genius documentation (please refer this). I was able to connect to the public dataset. However, I cannot connect to my own postgres database (hosted on Amazon AWS). I am certain I am entering the correct credentials for the database connection.

Environment

• Chaos Genius version: 0.5.1
• OS Version / Instance: Ubuntu 20.04
• Deployment type: Deployed locally by cloning the repository and using the docker-compose up command

Current behavior

After deploying chaos-genius locally and starting all services using the docker-compose up command, the home page for chaos-genius shows on localhost:8080. On clicking the “Add Data Source” button on the homepage, I am taken to the “Add Data Sources” page. After entering all details correctly for my own postgres database, I click the “Test Connection” button. a “Loading…” message appears. This never changes to “Add Data Source” and just changes back to “Test Connection”.

Steps: to reproduce:

1. Clone the repository: git clone https://github.com/chaos-genius/chaos_genius
2. Change into the chaos_genius directory: cd chaos_genius
3. Start services: docker-compose up
4. Navigate to localhost:8080 in browser
5. Click “Add Data Source” button on homepage
6. Fill in all database connection details
7. Click “Test Connection” to test

Expected behavior

On clicking the “Test Connection” button, it should change to “Add Data Source”. Since the credentials are correct, “Test Connection” should be successful and this should happen.

Thanks @prathamSharma25, as the 5432 port of Postgres server was not publicly accessible and you were accessing it using port forwarding via ssh tunnel, and cg backend containers were not able to access ports on localhost outside container we were able to do following to resolve this:

• Used IP of docker0 bridge in Host field of Add datasource form, can get this IP by running ip -4 addr show docker0 | grep -oP '(?<=inet\s)\d+(\.\d+){3}'
• while ssh tunneling bind source port to 0.0.0.0 instead of localhost, by default ssh tunnel will port forward to localhost, cmd to use ssh -L 0.0.0.0:<host port> ... , reference for ssh tunnel => ssh -L [LOCAL_IP:]LOCAL_PORT:DESTINATION:DESTINATION_PORT [USER@]SSH_SERVER

Hi @rjdp, thank you for your response. I have made sure to enter all database connection details correctly (with correct port number for my DB). I too beleive it is a timeout issue, but I can’t know for sure. If it really is a timeout issue, what do you suggest I do to connect to my database? I have joined the Slack channel. Thanks again.
