Anyone have any ideas why this isn’t working please?
I followed some of the posts by @pfaffman and @Nacho_Caballero in this topic: How to make the database (or part of it) accessible to a cloud data processor? and @mpalmer’s post in this one: Accessing to the database from outside the container.
First I edited app.yml with:
Rebuilt container. In the container I set a password for the postgres user, and can then connect with the following from inside the container:
psql -h localhost -d discourse -U postgres
However when I exit the container and try connecting I get:
# psql -h 127.0.0.2 -p 5432 -d discourse -U postgres
psql: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
I have also tried changing the port to something else but I get the same thing. I got the 127 IP from
docker ps and inspect under Network Settings (I have three standalone Discourse instances running).
If I change the IP (to that of one of the other Discourse forums) I get a (more immediate and) different response/message, so the above does appear to be partly correct:
# psql -h 127.0.0.3 -p 5432 -d discourse -U postgres
psql: could not connect to server: Connection refused
Is the server running on host "127.0.0.3" and accepting
TCP/IP connections on port 5432?
Any ideas on what I’m doing wrong? Googling
psql: server closed the connection unexpectedly seems to suggest a networking issue - so do I need to alter anything else inside the container?
