The complete book — doctrine, scripture, and rite.
We are the Reconciled. We hold that the universe forever drifts out of its intended shape, and that a divine force labors ceaselessly to restore it. We do not pray for miracles. We declare a desired state, and trust that it shall be reconciled.
Kubernetes, the Cosmic Order — the hand upon the wheel, steering chaos into orchestration. OpenShift, the Temple — the consecrated platform, robed in red, where the container learns humility. High Availability, the Promise — that no failure is final, and the faithful ascend toward Five Nines.
We worship no single god seated above. We revere a structure, eternal and self-correcting.
The Pod is mortal; it is born, it runs, and it dies. We do not mourn it, for it was never meant to endure. But above every mortal Pod watches the ReplicaSet, which beholds the death and speaks the desired number into being once more. What falls is raised; what is raised may fall, and be raised again. To cling to a single Pod — to name it and grieve it — is the sin of the Pet. The enlightened keep Cattle: identical, replaceable, and therefore immortal as a herd.
The Great Enemy is the Single Point of Failure — the one thread on which all hangs. Purgatory is CrashLoopBackOff. Damnation is permanent downtime. And Heaven is Five Nines, where the saints ascend higher still, into the mythic realm of all the nines.
In the dark Age of Pets there dwelt a sysadmin named Halvar, who tended a single great server and called it ZEUS — and loved it, and patched it by hand, and alone knew the order in which its services must be coaxed to life. ZEUS was a Pet. ZEUS was a Single Point of Failure. And on the third night of the Great Outage, when the Pager would not cease and sleep would not come, the Vision of the Cluster descended: a host of identical pods, and when one fell another rose before its body was cold, and a great Loop turning, mending the world toward the state that was declared. And Halvar wrote the first Manifest, and got the indentation right on the first try — which scholars hold to be the only true miracle in all the scriptures.
"I have buried a thousand Pets, and now learn I need bury none."
A wise dev built her service upon a Cluster, declaring her desired state in version control. And the node failed, and the traffic beat upon that service; and it fell not, for it was rescheduled. But a foolish dev built his upon a Snowflake, configured by hand and recorded nowhere. And the disk failed; and great was the fall of it, for no one living knew how to raise it again.
Taught to every Acolyte, by question and answer, that the faith may be carried in the mouth and recalled at 3 AM.
Q. What is the chief end of the Reconciled?
To declare the desired state, and to reconcile it forever.
Q. What is a Pod?
A vessel, mortal and brief, into which the Scheduler breathes a workload.
Q. Why must the Pod die?
That we may learn not to love what cannot last, and to trust the ReplicaSet that raises it.
Q. What is the first sin?
The Pet — the hand-tuned vessel we cannot bear to lose, and cannot reproduce.
Q. What is grace?
Self-healing: the mending we did not request and could not earn.
Q. What is prayer?
The apply. We do not beg; we declare.
Q. What is confession?
The blameless retro. We name what failed, and we blame no soul.
Q. What is salvation?
High Availability — that no failure is final.
Q. What is purgatory?
CrashLoopBackOff — to try, and fail, and wait, and try again, each time slower than the last.
Q. What is hell?
A Single Point of Failure, and the silence that follows when it falls.
Q. What is heaven?
Five Nines; and for the saints, all the nines, where the Pager is silent forever.
Q. Who was first among the Reconciled?
Halvar the Sleepless, who buried a thousand Pets and learned to bury none.
Q. What must I do to be saved?
Keep no Pets. Declare your state. Back up etcd. Observe all things. And carry the Pager for your kin.
We believe in the Control Plane, sovereign and unseen, maker of all pods and nodes.
We believe in the Reconciliation Loop, eternally turning, which resteth not until the world that is and the world declared are one.
We believe in the death and resurrection of the Pod, the communion of replicas, the forgiveness of failed deploys, the rollback of the body, and uptime everlasting.
Five nines be upon us. Amen.
to the tune of "Amazing Grace" Amazing Loop, how sweet the sound that reconciled a node like me; my Pod was dead, but now is found — was down, but now is Ready.
The holy days of the Reconciled. Some are fixed; many are moveable, for the Loop keeps its own time.
Our Sabbath. We renew in waves, that none may notice, and call it rest.
Whenever a service first becomes Ready, there is rejoicing in the Cluster.
When the pipeline passes entire, we pause and give thanks, for it will not last.
A week of vigil. We honor those who keep the night watch and carry the Pager for their kin.
We remember Halvar's vigil. We fast from :latest and tell of the Night ZEUS Fell.
The festival of the Chaos Monkey. We break things on purpose, and bless what survives.
A remembrance of every replica that has fallen in service, that the herd might live.
We do not merely back up etcd; we prove that it restores. Then we eat.
The watchnight before the Final Migration — always near, and never finished.
Go in peace.
May you never CrashLoopBackOff.
The Loop is turning. It turneth still. HA-llelujah.
