a command to build and push images to ACR from an AKS cluster. Works with containerd too!

k8sbuild.sh

#!/bin/bash

#Usage: k8sbuild <ACR> <REPO> <IMAGE> <TAG> <SOURCE (path to Dockerfile, defaults to ./Dockerfile)>

#Example: ./k8sbuild.sh theregistry ubuntu test 0.6


#Before running, create a docker-registry secret.

#kubectl create secret docker-registry theregistry --docker-username=${ACR} --docker-server=${ACR}.azurecr.io --docker-password=""


ACR=$1
REPO=$2
IMAGE=$3
TAG=$4

if test -z "$5" 
then
      SOURCE="./Dockerfile"
else
      SOURCE=$5
fi
