Here is a simple development environment,
Clone Git repository to your environment
# git clone git@github.com:grgizem/simplecluster
Install vagrant, https://www.vagrantup.com/docs/installation/
# apt install vagrant
Install virtualbox, https://www.virtualbox.org/wiki/Downloads
# apt install virtualbox
You can use following environment variables to configure your environment:
KUBERNETES_MEMORY: Memory value of kubernetes
KUBERNETES_MASTER_MEMORY: Memory of kubernetes master, this will override KUBERNETES_MEMORY (default: 1280)
KUBERNETES_NODE_MEMORY: Memory of kubernetes nodes, this will override KUBERNETES_MEMORY (default: 2048)
Also you can set following environment variables to use on deployments, otherwise it will ask on every deployment,
DOCKER_USERNAME: Username that you use to login to https://hub.docker.com
DOCKER_EMAIL: Email address that you use to login to https://hub.docker.com
DOCKER_PASSWORD: Password that you use to login to https://hub.docker.com
Start your development environment up with,
# vagrant up
After your environment is up, deploy the application easily with following command. Note that you will need a Docker ID. If you do not have a Docker ID, head over to https://hub.docker.com to create one.
# ./scripts/deploy.sh
You can list applications and services on cluster,
# ./scripts/list.sh
You can deploy local code changes to development environment with,
# ./scripts/deploy.sh
You can access to service from your browser after executing,
