Is it possible to query all known domains from a DNS server? Normally you ask a DNS server to resolve a domain like `example.org` to the corresponding IP address. The server either knows the answer right off the bat (cached or authoritative), or where it might be found. Ignoring the latter option, would it be possible to query a DNS server for all the doma...

Why is SQL usually written in CAPS? Why are keywords in SQL usually written in capital letters? For example: ```sql SELECT FROM person WHERE mood = 'happy'; ``` My understanding is that SQL is case insensitive, so the case doesn't actually make a difference? (more) |

A: Best practices for designing a central gateway/hub for microservices communication GraphQL instead of gRPC Assuming you do decide to implement a gateway, I'd consider implementing it as a GraphQL API instead of plain gRPC. I feel like your usecase is almost exactly what it's intended for. It too suports streaming, plus it's just a pleasure to work with in general. Easy to docume... (more) |

A: Best practices for designing a central gateway/hub for microservices communication How about a library instead? The traditional way of reducing code duplication among separate software packages is to wrap the common bits in a library and use it where ever the functionality is needed. Each microservice would still be talking directly to the external service, but most of the co... (more) |

A: How to disable jobs in GitLab CI after they are successfully executed I don't think there exists a straightforward solution. Likely you can achieve this with `rules` but you'll have to define and finetune them on each of the jobs. (template jobs may help a bit here.) I.e. configure some jobs to only run on merges and others only on commits etc. The last resort wo... (more) |

Right so you mean following situation?
1. A commit is pushed to branch A and a pipeline is triggered.
2. The branch gets merged to `main` and the pipeline is triggered again.
3. (optionally) a tag gets pushed to the repository, triggering yet another pipeline. (more) |

A: Keep failed CronJob Pods around in Kubernetes There are a few fields that play into this, but the gist of it is to set the Pod's `restartPolicy` to `Never`. This doesn't mean that the Job only tries once. Rather, instead of restarting the container inside the Pod on failure, a new Pod will get scheduled until the Job's `backoffLimit` is reached ...

| Question | — |
Keep failed CronJob Pods around in Kubernetes It seems like pods created by a Kubernetes CronJob (or rather Job) are deleted as soon as they fail. This makes it difficult to figure out what went wrong (unless you have Prometheus or some other log aggregator in use). Is there a way to keep the pods of the failed Jobs around for a while to faci... (more) |

A: Helm delete old release revisions You don't need to do anything. Helm prunes old release secrets once their number exceeds 10. More specifically, `helm upgrade` command has an integer option `--history-max`, that allows you to specify the max amount of revisions to keep around. It defaults to 10. (more) |

Helm delete old release revisions Helm keeps track of releases and their revisions by creating a kubernetes `Secret` each time a chart is installed, upgraded etc. These are of course useful in case you want to rollback, but they do pile up.

A: What does an exclamation mark mean in a GraphQL schema? It's a type modifier that means that the field is non-nullable. That is, when uploading these types you must provide values for these fields, and in turn the server promises to always populate the field in query responses (or return an error if it cannot be done). Official docs. (more) |

A: UID of nonroot user in distroless container images You don't actually need the UID in that particular example.

I'm indeed using rancher, but it's really more a part of the answer than the question. This is mostly a question about understanding what can cause such an error message. There could be other non-rancher-related causes too. (more) |

A: Kubectl exec: "Error from server (BadRequest): Upgrade request required" Ok I got it working again. The issue was that I had updated my kubeconfig file, and the `current-context` setting had changed. This setting essentially selects which cluster kubectl targets. Now the cluster wasn't a wrong one per se, it just wasn't a direct route. This is a `rancher` managed cl... (more) |
