PtahStand up the lab
A four-node kind cluster, the chart from a package, and every image pinned by digest.
What it shows. What the other runs are against, and how to tell an install that finished from one that started.
Where it starts. The lab make demo-up builds, with nothing of the runs in its namespace. This run is the setup the others start from, and its checks are installation evidence rather than lessons.
A replay of a verified run, not a live cluster. 8 checks held while it was recorded. Play types it out in the frame below; the transcript is the same session, already there.

What was checked
Every step states what has to hold before its output may be published. A condition is read as its type, status and reason on the live object, never as a phrase in a message.
| Step | Claim | Held |
|---|---|---|
| 1 | exits 0, prints "kubernetes", prints "kind", prints "operator", prints "executor", prints "ptah" | yes |
| 2 | exits 0, prints "successfully rolled out" | yes |

What the commands read
A session is repeated, not admired, so every name in it is one your own environment can carry. There is nothing else: no helper of ours stands between a command and the cluster, and the recorder refuses a step that reads a name this list does not hold. The commands arekubectl, ptah and kubectl ptah, each of which you install once; the last one is the operator’s own client. They run from the root of a clone of this repository, which holds the files they name: the SQL under demo/schemas, demo/migrations,demo/migrations-checkpoint and demo/mysql, the reference data underdemo/reference, and the manifests under demo/manifests.
- KUBECONFIGthe cluster the commands run against
- NAMESPACEthe namespace the resources and their database credentials live in
- OPERATOR_NAMESPACEwhere the chart installed the operator
- CONTROLLERthe controller Deployment’s name, from that release
- EXECUTOR_IMAGEthe executor image the chart runs, its
executorImagevalue - REGISTRY_IN_CLUSTERthe registry address a Pod in the cluster resolves
- PTAH_OCI_REGISTRYthe registry address the push goes to
- PTAH_OCI_USERNAMEthe account that push uses, read by
ptahitself - PTAH_OCI_PASSWORDits password, which no command prints
The last two are how a CI job hands ptah a registry credential. On a workstation,ptah oci login stores it once instead, reading the password from a prompt or from standard input rather than from the command line.
The registry has two addresses, the way a registry in an ordinary deployment does: a push goes to PTAH_OCI_REGISTRY, and the resource names REGISTRY_IN_CLUSTER with the same repository and digest. The registry Secret a resource names says which address its credential is for, and the operator sends it to no other.
The lab itself appears in one command, demo/bin/lab versions in Stand up the lab, which says what the lab is made of. What a run starts from is its preparation, which is not recorded; Where it starts above says what that is and which run ends there. Rundemo/acceptance/reproduce.sh to watch Approve a plan repeated from a directory where the lab’s scripts do not exist, by an account that may not create a Job, with the plan approved by a second account that may create neither a schema nor a Job, and then the same schema published with ptah schema push and moved to its next revision withkubectl ptah set-source.
The same changes, as edits
Each kubectl ptah command that changes a resource changes one field of it, so the same change is an ordinary edit, with kubectl edit ptahschema storefront -n "$NAMESPACE"or in a manifest you apply; the runs that keep their resources as files underdemo/manifests make their changes that way. What the commands add is checking: set-source takes only a reference pinned by digest, changes nothing while an Apply may be running, and changes nothing another writer changed since it read the resource.
| Command | The line it changes |
|---|---|
kubectl ptah suspend | spec.suspend: true |
kubectl ptah resume | spec.suspend: false |
kubectl ptah set-source --oci | spec.desired.ociRef of a schema, spec.artifact.ociRef of a migration |
kubectl ptah refresh | the annotation operator.ptah.run/read-requested-at, set to the time of the request |
An approval is not one of them. It is an object of its own, created once by the person who decided: kubectl ptah approve --dry-run client prints it as YAML for a repository, to be created with kubectl create, and never edited afterwards.
The scenario is demo/scenarios/lab-setup.yaml, and make demo replays the whole set against a lab of your own. All recorded runs.
