Hello. I am trying to use this image with the following arguments:

docker run --rm 
-e POSTGRES_INITDB_ARGS="--wal-segsize=1024"
-v /home/user/db/12/main:/var/lib/postgresql/12/data 
-v /home/user/db/13/main:/var/lib/postgresql/13/data 
tianon/postgres-upgrade:12-to-13

but it fails with this output:

*failure*

Consult the last few lines of "pg_upgrade_dump_116017.log" for
the probable cause of the failure.
Failure, exiting

Where can I found that logfile pg_upgrade_dump_116017.log please?

you can mount a folder in your host to /var/lib/postgresql and then you'll see the log.
Example:
docker run --rm
-e POSTGRES_INITDB_ARGS="--wal-segsize=1024"
-v /home/user/db/12/main:/var/lib/postgresql/12/data
-v /home/user/db/13/main:/var/lib/postgresql/13/data
-v /home/user/:/var/lib/postgresql
tianon/postgres-upgrade:12-to-13

also u can do something like

# find out the hash of  the last run docker
docker ps -a | head
docker commit THE_HASH test1
docker run -it --rm --entrypoint=sh test1

# in the container
ls -l
cat pg_upgrade_dump_116017.log
