I had the need to pipe data into a container being run in kubernetes. I found out that whatever combination of -i, -t or --attach I specified, the containerised process never received an EOF. And if it did, all it received was the EOF; not the data I piped into it. Unless I carefully went through all flags, and realised that --restart=Never solves it:

cat example.yaml | kubectl run -i --image img name --restart=Never

Recently when refactoring a Vue 1.0 application, I utilized ES6 arrow functions to clean up the code and make things a bit more consistent before updating to Vue 2.0. Along the way I made a few mistakes and wanted to share the lessons I learned as well as offer a few conventions that I will be using in my Vue applications moving forward.

The best way to explain this is with an example so lets start there. I'm going to throw a rather large block of code at you here, but stick with me and we will move through it a piece at a time.

<script>

// require vue-resource...

new Vue({

JQ to filter JSON by value

Syntax: cat <filename> | jq -c '.[] | select( .<key> | contains("<value>"))'

Example: To get json record having _id equal 611

cat my.json | jq -c '.[] | select( ._id | contains(611))'

Remember: if JSON value has no double quotes (eg. for numeric) to do not supply in filter i.e. in contains(611)

	DUMP
	// pod-name name of the postgres pod
	// postgres-user database user that is able to access the database
	// database-name name of the database
	kubectl exec [pod-name] -- bash -c "pg_dump -U [postgres-user] [database-name]" > database.sql

	RESTORE
	// pod-name name of the postgres pod
	// postgres-user database user that is able to access the database
	// database-name name of the database

	#!/bin/bash
	set -e
	set -o pipefail

	# Add user to k8s using service account, no RBAC (must create RBAC after this script)
	if [[ -z "$1" ]] \|\| [[ -z "$2" ]]; then
	echo "usage: $0 <service_account_name> <namespace>"
	exit 1
	fi
