Describe the problem

When trying to launch the peertube docker container i get the following crash

I've tried to define redis instance information in .env

# Database / Postgres service configuration
POSTGRES_USER=peertube
POSTGRES_PASSWORD=peertube
# Postgres database name "peertube"
POSTGRES_DB=peertube
# The database name used by PeerTube will be PEERTUBE_DB_NAME (only if set) *OR* 'peertube'+PEERTUBE_DB_SUFFIX

Can you try to remove PEERTUBE_REDIS_* variables from your env file?

[Juliasmatius]

Sure!

The log for that is https://pastebin.com/8kGbr7RF

[Chocobozzz]

Can you go inside your peertube container and try to ping redis? (ping is not in the peertube container but you can try curl -v redis:6379)

[Juliasmatius]

I seem to be getting a response.

root@v25159:~/docker/peertube# docker exec -it peertube-peertube-1 bash
root@df89efbf35b3:/app# curl -v redis:6379
*   Trying [2001:db8:2::2]:6379...

Hope this solves it: https://github.com/Chocobozzz/PeerTube/commit/f4339cfb72ac80c1c68059496da99797c4a0484b

The IPv6 2001:db8:-Range is for documentation only.

That change requires line 52 of the compose file to be changed to the container stairs up. I set it to ipv6_address: fdab:e4b3:21a2:ef1b:0000:0000:0000:0123 for testing. But i still get the same error. log

I am also not a 100% sure i modified the compose file correctly so thats here https://pastebin.com/J3wR0CPW
