In this commit, the code compiles and passes make check. But we currently can't test anything else, because the manifests/charts still use API groups that are obsolete in this k8s version.

The replica scaling test for self-sharding requires the Deployment name "varnish-ingress" for the viking service.

This is the SNI sent in the client TLS connection to a backend. We use VMOD dynamic for backends represented by an ExternalName Service (likely the common use case for TLS onload). VMOD dynamic does not have the authority field that klarlack makes available for standard backends. But if the host_header field is set for a VMOD dynamic director, the VMOD uses that value for the SNI. So if the BackendConfig authority field is set, we also assign its value to the host_header field. Since BackendConfig also has a separate field for host_header, both of them could be conceivably set to different values. If we find that the two fields are set to non-empty, conflicting values, the controller emits a SyncFatalError, and the BackendConfig is not synced.

This uses haproxy for TLS connections to IngressBackends, and the via feature of the klarlack implementation of Varnish. See: https://github.com/varnishcache/varnish-cache/pull/3128 Adds the spec.tls object to the BackendConfig CRD, which configures TLS onload for a backend. Limitations: currently only verify:false and the maxConn settings are implemented. Specification of CA certificates and the stick table configuration for haproxy are not yet implemented. Currently TLS onload may be only specified for one backend (no more than one BackendConfig). Adds the CLI option -varnishImpl to the controller. TLS onload is only supported if this option is set to "klarlack". Otherwise, the presence of the tls object in a BackendConfig leads to a SyncFatalError, with a message that it's only supported for klarlack, and the BackendConfig is not synced. If the backend Service specified for TLS onload has type ExternalName, then 3 server instances are configured for the haproxy backend. This value is currently hard-wired, and may be made configurable in a future iteration. For any other Service type, there are as many haproxy server instances as there are Endpoints (Pods) in the k8s cluster. If maxConn is not specified in the BackendConfig, it defaults to 2000 (the haproxy default).

If changes did not trigger a klarlack build, gitlab CI would file this complaint: Found errors in your .gitlab-ci.yml: 'build:ascn' job needs 'build:klarlack' job but 'build:klarlack' is not in any previous stage despite the fact that the ci file lints just fine. IIUC, the issue is that for the triggered pipeline, the klarlack build job just would not exist. In this case, we can build ascn on top of the previous klarlack build.

Here we are going to move the custom software install (watermarker etc) which we need for the primary sponsor. For now, the new container is just the same as the klarlack image

For this it is necessary to abandon go get to download k8s-crt-dnldr, and use git clone && make instead. The reasons for that are detailed in commit message fe1fc4f of the k8s-crt-dnldr repo.

The self-sharding field in VarnishConfig now has a mandatory field rules. This is an array of at least one object with a mandatory field shard and an optional field conditions. spec.self-sharding.rules[n].shard configures sharding in the fields key, digest and primaryOnly (all optional). spec.self-sharding.rules[n].conditions, if specified, is an array of at least one condition, which specifies a boolean expression. It is the same as conditions used for other contexts such as rewrites. The rules array is evaluated in order as an if-elsif-else sequence. This means that if any element of the array specifies no conditions, it MUST be the last rule in the array. In an array of length > 1, it becomes the else case. This constraint is trivially satisfied if there is only one rule. It is currently *not* enforced (would be suitable for a webhook validation). The fields probe and max2ndttl are now top-level fields under self-sharding, both optional.
