Kubernetes for People Who Have to Run It

For the engineer who already has this in production and did not choose it. The request path outside in, scheduling and node pools, the address space that runs out while the hardware sits idle, and a control-plane bootstrap worked through its real failure sequence to a conclusion.

Kubernetes for People Who Have to Run It

Брифинг

This is the highest level in the Library and it does not open by explaining what a container is for. It assumes you run something. Somebody else built the cluster, or you built it in a hurry two years ago, and you are now the person who gets rung when it stops. If you are still deciding whether to adopt this platform at all, read the fourth module of Securing a Cloud Estate You Didn't Build first — it works through a client who asked for a Kubernetes-scale answer to a spreadsheet-scale problem, and it gives you the words to refuse. That argument is finished and this segment does not reopen it. This one starts one step later. Everything here is taught from something that failed. You will apply an Ingress that is accepted and does nothing, schedule pods that never run, resolve a service name perfectly and connect to nothing, and fill a machine with 32 idle cores and 96 GB of untouched memory until it refuses the next twenty-six pods. That last one is the best technical moment in the source material: a node with headroom for around four hundred pods that can only be given 256 internal addresses per interface, so full-mesh communication caps density long before the processor does. The last module builds a control plane from nothing on a throwaway host. It fails four times first — a leftover file, forwarding disabled, a port already taken, and a bootstrap that hangs for four minutes and then gives up with an error that does not name the cause. The bring-up in the source notes stops at that hang, unfinished. This one finishes it. The thread running through all four modules is a single habit: in this platform a green tick means an object was accepted, and says nothing whatsoever about whether anything acted on it.

Все учат эту платформу изнутри наружу, а потом приходится отлаживать её снаружи под давлением в 3 утра. Этот модуль строит карту в направлении, из которого приходит инцидент, и заканчивается той…

3 уроков·1h 56m

Разместить pod может кто угодно. Работа в том, чтобы это расположение пережило встречу с одиннадцатью другими инженерами, которые о нём ничего не знают, и это требует обеих половин механизма, который…
03 Сеть и адресное пространство, которое закончилось
3 уроков·2h 41m

Две лабораторные работы в этом модуле создают кластер, который здоров по каждой метрике, собираемой вашим мониторингом, и не может запустить другую рабочую нагрузку. Вторая не оставляет никаких…

Большинство людей, читающих это, никогда не будут строить плоскость управления, и это разумное решение, а не пробел в знаниях. Сделайте это один раз в любом случае: развертывание — единственный…

Advanced Securing a Cloud Estate You Didn't Build You have been handed a cloud estate built by five companies that merged, spread across two providers, with roughly 740 resources, fifteen spreadsheets of policies and read-only access. This segment is the method for getting an opinion worth having in four weeks, and the prioritised week-one plan you hand over at the end of it.

Intermediate Locking Down Identity — Conditional Access and Privileged Access Identity is the one thing that spans a whole tenant, and most people who administer it have never configured it deliberately. This segment builds the controls, one at a time, in report-only first: a conditional access set enforced without locking anybody out, privileged roles moved from permanent to eligible, two emergency access accounts that have actually been used, and the count of permanently privileged accounts taken from eleven down to two.

Intermediate Infrastructure as Code The tool the cloud course refused to teach. Build the same resource three ways and time the difference, then live in the file that actually breaks: the state file, its secrets in clear, its lock, and the recovery when it and the world disagree. Everything is run against a pinned Terraform and a local provider, every lab states a cost ceiling and ends by tearing down, and the segment never leaves you with anything running or billing.
