pmm-kubernetes-bash

Bash scripts to manage PMM Server and Clients.

This project is meant for cases where frameworks like Ansible or Puppet are not desirable for some reason, or not necessary.

Configuration

Copy the configuration template:

cp conf.sh.default.sh conf.sh

Also copy the example 'values' file:

cp example-values.yaml values.yaml

conf.sh and values.yaml contain all the configuration. Each option is documented in the files themselves.

NB! Make sure the values are the same for PMM_SERVER_PASSWORD in conf.sh and pmm_password in values.yaml.

These file are ignored by git.

Notes about the values.yaml file

The example-values.yaml file has the service type as ClusterIP, so it can use the separate LoadBalancer (see below).

Note also that the storageClassName used is a magical one which in the Diamond Kubernetes cluster will give us node-local storage.

Usage

Currently scripts usage is documented in the scripts themselves. To see their built-in help:

HELP=1 ./pmm-server.sh
HELP=1 ./pmm-client.sh

ACTION=INSTALL pmm-server.sh outputs, amongst other things, the IP of PMM Server. But you may need this information at any later time. To obtain it, run:

./get-ip.sh

It only outputs the IP, so it can be piped to another script.

Load balancer

Currently, the project needs a separate LoadBalancer to work. This has a fixed IP address which was assigned especially for PMM.

Install this with:

kubectl apply -f ./pmm-loadbalancer.yaml
