git-version not found about pg_auto_failover HOT 9 CLOSED

git-version was introduced in 5a99c5a. But I do not see where it is created.

from pg_auto_failover.

Hi @lgammo ; the only build system supported for the project is the Makefile. Please see about using the Makefile to drive your work there, or at least to create the git version files. See make version for instance.

from pg_auto_failover.

Thanks for the reply.

1. I was following the tutorial, which did not mention anything about building anything.
2. I commented out the line that copies git-version.h in the top Dockerfile. That seems to get things to compile and build.
3. I did build using make at the top of the repo.
4. The build system expects postgres to be installed natively for some reason.
5. Once I disabled the copy of git-version.h in the Dockerfile, the tutorial did build and I got the images and contains and I managed to get them started.
6. HOWEVER, the monitor container failed. When I did this step:
7. docker compose exec app psql' from the tutorial, I got:
   psql: error: connection to server at "node1" (172.21.0.3), port 5432 failed: FATAL: no pg_hba.conf entry for host "172.21.0.2", user "tutorial", database "tutorial", SSL encryption

Any ideas?

1. I was following the tutorial, which did not mention anything about building anything.

Oh I see. That's where the docker-compose build comes from. Did you run that command from the docs/tutorial sub-directory of the source checkout like the tutorial sayth you should? It seems to me that the errors you had could be explained easily if you mistakenly ran that command at the top-level directory from the checkout.

4. The build system expects postgres to be installed natively for some reason.

Sure, the source code for pg_auto_failover has some build-time dependencies with PostgreSQL development headers and libs. Depending on your packaging system and OS of choice, that might mean installing all of the Postgres packages is required.

7. docker compose exec app psql' from the tutorial, I got:
   psql: error: connection to server at "node1" (172.21.0.3), port 5432 failed: FATAL: no pg_hba.conf entry for host "172.21.0.2", user "tutorial", database "tutorial", SSL encryption

I will need more information to be able to debug that one. First, let's make sure you are running the actual tutorial commands from the right place.

from pg_auto_failover.

I am running the tutorial from pg_auto_failover/docs/tutorial. In one terminal I do ' docker compose up app monitor node1 node2
', and in an other terminal I do ' docker compose exec app psql' and that's when I get:
psql: error: connection to server at "node1" (172.21.0.4), port 5432 failed: FATAL: no pg_hba.conf entry for host "172.21.0.2", user "tutorial", database "tutorial", SSL encryption

Logs from the 'docker compose up app monitor node1 node2' command.

node1.log

I put the logs from the entire set of dockers images in the hope they are useful. The logs from the 'docker logs tutorial-app-1' container are like this:

And it stopped after that.

The tutorial docker images appear to be fine and I am able to perform switchover and other tests.

Thanks.
