Hey @aniruddha2000, I'm managing your ondemand environment ond-yak. I've successfully transitioned from phase "preheated" to "provisioning".

How to Connect

Retrieve kubeconfig to interact with the environment with kubectl ske (assuming you're connected to the prow-trusted cluster):

gardenctl target --garden prd --project 74140853d0 --shoot prow-trust
kubectl ske connect ondemand ond-yak

To connect to the API, you can retrieve the Password from the prow-trusted cluster:

export BASIC_AUTH_USERNAME=$(kubectl get -n ondemand secret ond-yak-credentials -ojsonpath='{.data.username}' | base64 -d)
export BASIC_AUTH_PASSWORD=$(kubectl get -n ondemand secret ond-yak-credentials -ojsonpath='{.data.password}' | base64 -d)
export PROJECT_ID=$(kubectl get -n ondemand secret ond-yak-credentials -ojsonpath='{.data.projectID}' | base64 -d)
export SNA_PROJECT_ID=$(kubectl get -n ondemand secret ond-yak-credentials -ojsonpath='{.data.snaProjectID}' | base64 -d)
export SKE_API=https://ske-api.ing.ond-yak.ci.ske.eu01.stackit.cloud

[ske-prow]

Hey @aniruddha2000, you've asked for an ondemand environment. The OnDemandEnvironment ond-yak has already been assigned to this issue/PR, so I can't allocate another. 🫣

Hey @aniruddha2000, I'm managing your ondemand environment ond-yak. I've successfully transitioned from phase "provisioning" to "destroying".

Hey @aniruddha2000, you've asked me to delete the ondemand environment associated with this issue. I successfully destroyed the OnDemandEnvironment ond-yak.

/ondemand help

[ske-prow]

@aniruddha2000: The following commands are available for ondemands:

• /ondemand create [OPTIONS]: Create an ondemand
• /ondemand delete: Delete an existing ondemand that was associated with this PR/Issue
• /ondemand edit [OPTIONS]: Edit an existing ondemand
• /ondemand (move|transfer) --issue/--pull Move an existing ondemand
• /ondemand help: Print this message

Note that by default your ondemand will be deleted when the issue/PR is closed.
You can disable this by setting the label ondemand/skip-deletion. Deletion
will also be triggered after 1 week, which can be customized via the --ttl
flag.

Available `flags`

You can specify arguments as if using a CLI, e.g. /ondemand --help. Available arguments are:

      --class string                   If specified, sets OnDemandEnvironment.spec.class to the given value. Useful for testing changes to the ondemand controller.
      --feature feature                Optional features to enable on the ondemand. (default [])
      --fresh                          If true, a not yet provisioned ondemand is assigned. Otherwise a preheated ondemand is preferred.
  -h, --help                           Displays the help message
      --initial-cluster-type string    Type of the ondemand's initial cluster: shoot (default) or autonomousshoot
      --issue string                   Target Issue when moving ondemands, like 'stackitcloud/ske-base#123' or a full URL. Synonymous with pull.
      --pull string                    Target PR when moving ondemands, like 'stackitcloud/ske-base#123' or a full URL. Synonymous with issue, which takes precedence.
      --ske-base-branch string         Override the ske-base GitRepo branch ref
      --ske-components-branch string   Override the ske-components branch ref.
      --ske-stages-branch string       Override the ske-stages GitRepo branch ref
      --ttl duration                   Time to live for the ondemand (e.g. '168h'). It will be deleted automatically once the time has passed. (default 168h0m0s)

Additionally, you can enable the following features when you create an ondemand

* private-networking<br>

by using /ondemand create --feature <name>=<config>.

The config will be parsed by Helm's strvals which is a compact format of YAML. Thus, if you have a YAML configuration, e.g.

fieldA:
subFieldA: valueA
fieldB:
subFieldB:
subSubFieldB: valueB

you would pass it as 'fieldA.subFieldA=valueA,fieldB.subFieldB.subSubFieldB=valueB'
