Mysqldump from Docker container

docker exec -i mysql_container mysqldump -uroot -proot --databases database_name --skip-comments > /path/to/my/dump.sql

OBS

• This will generate a dump.sql file in your host machine. Awesome, eh?
• Avoid using --compact on your dump. This will make MySQL check your constraints which will cause troubles when reading your file (damm you MySQL). And don't use --force to fix this scenario: recreate your dump without --compact ¯_(ツ)_/¯

Multiplatform (amd64 and arm) Kubernetes cluster setup

The official guide for setting up Kubernetes using kubeadm works well for clusters of one architecture. But, the main problem that crops up is the kube-proxy image defaults to the architecture of the master node (where kubeadm was run in the first place).

This causes issues when arm nodes join the cluster, as they will try to execute the amd64 version of kube-proxy, and will fail.

It turns out that the pod running kube-proxy is configured using a DaemonSet. With a small edit to the configuration, it's possible to create multiple DaemonSets—one for each architecture.

Steps

Follow the instructions at https://kubernetes.io/docs/setup/independent/create-cluster-kubeadm/ for setting up the master node. I've been using Weave Net as the network plugin; it see

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?
