Generate Rancher 2 cluster/node agents definitions

This is not official documentation/tooling, use with caution

This generate the Kubernetes definitions of the cattle-cluster-agent Deployment and cattle-node-agent DaemonSet, in case it's accidentally removed/server-url was changed/certficates were changed. It is supposed to run on every cluster Rancher manages. If you have custom clusters created in Rancher, see Kubeconfig for Custom clusters created in Rancher how to obtain the kubeconfig to directly talk to the Kubernetes API (as usually it doesn't work via Rancher anymore). For other clusters, use the tools provided by the provider to get the kubeconfig.

IMPORTANT: You get the cluster/node agents definitions from Rancher, and you apply them to the cluster that is created/managed so you need to switch kubeconfig to point to that cluster before applying them.

Set up a 3 node HA rancher cluster.

This will create and prep nodes for RKE. This uses the default vpc and subnets.

We create:

• SSH Key Pair
• Security Groups
• 3 Instances
• ELB for 80/443 points to the 3 instances.

// Just before switching jobs:
// Add one of these.
// Preferably into the same commit where you do a large merge.

// This started as a tweet with a joke of "C++ pro-tip: #define private public",
// and then it quickly escalated into more and more evil suggestions.
// I've tried to capture interesting suggestions here.

# Converts a mysqldump file into a Sqlite 3 compatible file. It also extracts the MySQL `KEY xxxxx` from the
# CREATE block and create them in separate commands _after_ all the INSERTs.

# Awk is choosen because it's fast and portable. You can use gawk, original awk or even the lightning fast mawk.
# The mysqldump file is traversed only once.

# Usage: $ ./mysql2sqlite mysqldump-opts db-name | sqlite3 database.sqlite
# Example: $ ./mysql2sqlite --no-data -u root -pMySecretPassWord myDbase | sqlite3 database.sqlite
