SadServer task Bilbao url: https://sadservers.com/scenario/bilbao

After login and inspection of the issue, we get this picture:

Pod status

After googling I found an issue with nodeSelector - so I removed it from the manifest.yml file:

Remove nodeSelector

After removing - it needs to delete all pods, re-run manifest, and check with curl: Delete pods & run yaml file

Solution for Bucharest

Bucharest - url for task: https://sadservers.com/scenario/bucharest File edit:

If we run command:

PGPASSWORD=app1user psql -h 127.0.0.1 -d app1 -U app1user -c '\q'

We could see issue with access and file named "pg_hba.conf " If we open file, and we could see next lines:

host    all             all             all                     reject
host    all             all             all                     reject

If we dig manual for file - we could find that "reject" do that - reject any connection. So replacing with md5 word reject (use sudo for editing file and restarting services), and restart services with

sudo systemctl restart postgresql@13-main.service
