Hello fellow TCP users,

I am moving my homelab from Docker to Kubernetes (because I have nothing to do with my homelab anymore) and I am having an issue with services that need to be accessible both within the cluster and from the outside world on the same hostname.

For an example, supposedly you have two pods: A and B which are accessible via the Gateway with hostname a.example.com and b.example.com respectively. Pod A also need to contact Pod B so there are two ways to do this:

• Via b.example.com. This works but in this case, the traffic will go from pod A -> the boarder internet -> the loadbalancer -> the gateway -> pod B which is not very optimal.
• Via b.default.svc.cluster.local. This also works but in this case you lose:
  • TLS: because you bypass the gateway.
  • Configuration transparency: now you have to maintain a different internal hostname and another external hostname. For example Keycloak has a specific setting just for this case: https://www.keycloak.org/server/hostname#_utilizing_an_internal_url_for_communication_among_clients.

In Docker case, I can just set the alias of my reverse-proxy container to b.example.com and it is done. I am wondering is there anything I can do to get the traffic goes from pod A -> the gateway -> pod B in Kubernetes. Also is this a common issue or not because I don’t see a lot of articles about this issue on the internet :/

Thank you very much!

Hello,

I know it is strictly related to selfhosting but I don’t have a reddit account so please bear with me. I’ve been using a Blackblaze B2 bucket as the storage for my restic backup for my whole homelab for a while and recently when reading from that bucket it is so so so so so so slow and unreliable (a lot of unexpected EOF and interruption). I’ve tested this on several machines (including a VPS on Hetzer) and I can access other sites just fine. Their status page says nothing and I wonder is it just me or do some of you also experience the same thing ?

Also any alternative recommendation is welcome but I can not selfhost my S3 at the moment :(

Thank you very much!

Edit: this is the log for my restic check --read-data (something similar on Hetzner VPS).

Edit: After a day my restic check --read-data finished with no data corruption but it took a lot of retrying, even 7 retries to read the correct data :/ So I guess it is a sign for me to move to somewhere else.
