metal3: inject oci_registry_extra_ca_certs in ipa-downloader for IPA image OCI artifact download (fix air-gapped use-case) (!8086) · Merge requests · Sylva-projects / sylva-core

Related to #4136

Context: !7985 (merged) includes a change of behavior where the metal3 ironic-ipa-downloader initContainer fetches the IPA image from an OCI artifact; this created a regression for air-gapped deployment because nothing was in place to automatically use an internal OCI registry mirror.

This MR ensures that this works in air-gapped deployments:

fetch the OCI artifact from the OCI/container registry mirror
include the CA certs from oci_registry_extra_ca_certs in the ironic-ipa-downloader initContainer

Some of this is achieved thanks to a postRender, discussion is in progress with @nbelouin who contributes to the Suse upstream chart so that we don't need a postRender at some point in the future.

Testing

⭐ this MR depends on sylva-projects/sylva-elements/ci-tooling/ci-deployment-values!462 (merged)

Two environments having a registry_mirrors entry for registry.suse.org.

in my local dev env ✅ :

$ k -n metal3-system logs metal3-ironic-5f7484f6dc-jsj6r ironic-ipa-downloader |grep -3 "manifest fetch"
+ get_oci_tarball 172.20.136.39/proxy_cache_registry.opensuse.org/isv/suse/edge/containers/images/ironic-python-agent:3.0.8
+ local image_ref=172.20.136.39/proxy_cache_registry.opensuse.org/isv/suse/edge/containers/images/ironic-python-agent:3.0.8
+ local manifest_json
++ oras manifest fetch 172.20.136.39/proxy_cache_registry.opensuse.org/isv/suse/edge/containers/images/ironic-python-agent:3.0.8
+ manifest_json='{
   "schemaVersion" : 2,
   "mediaType" : "application/vnd.docker.distribution.manifest.list.v2+json",
...

but this isn't a full test because on my dev env, the PVC was already populated

in CI with a capo scenario with 🟢 metal3, this tests the deployment in capo infra
- while testing this, we hit an interop bug betwee oras and Harbor (details below)
- this has been solved in this MR by configuring CI, only for this artifact, to use an alternate non-Harbor registry
- -> depends on sylva-projects/sylva-elements/ci-tooling/ci-deployment-values!462 (merged)

🎬	Pipeline Scenarios	Available scenario list and description
🟢	Enabled units	Any available units name, by default apply to management and workload cluster. Can be prefixed by `mgmt:` or `wkld:` to be applied only to a specific cluster type
🔴	Disabled units	Any available units name, by default apply to management and workload cluster. Can be prefixed by `mgmt:` or `wkld:` to be applied only to a specific cluster type
🏗️	Target platform	Can be used to select specific deployment environment Available platform list and description
⚡	Pipeline control	`autorun`, `manual` or `blocking`. Can be used to override global config and start a deployment pipeline the required way

Global config for deployment pipelines

autorun pipelines
allow failure on pipelines
record sylvactl events

Notes:

Enabling autorun will make deployment pipelines to be run automatically without human interaction
Disabling allow failure will make deployment pipelines mandatory for pipeline success.
if both autorun and allow failure are disabled, deployment pipelines will need manual triggering but will be blocking the pipeline

Be aware: after configuration change, pipeline is not triggered automatically. Please run it manually (by clicking the run pipeline button in Pipelines tab) or push new code.
