Multipass + Cloud Config DevOps

These are cloud configuration files for production ready apps. Mount or clone this repo to your Ubuntu virtual machine and then run the following command to install a production ready app to your instance. These scripts are built around Multipass inparticular but can be deployed to and cloud-based ubuntu server.

Security Notice

These cloud init files add a passwords file under /home/ubuntu/.keyfile. Please save these passwords somewhere safe and then delete the file from your server. You should also update the ssh_authorized_keys variable under users for scripts you use or you will be giving me access to your servers. My public key is there as an example.

Pass Configuration during VM Creation

Ideally, you pass these cloud-init scripts during creatin of the VM. You need to update variables that are set in the runcmd module of the script you use. For example, using multipass you would run the following script to setup a WordPress server:

multipass launch --name wordpress --cloud-init wp-cloud-init.yml

This would create an Ubuntu instance with the host name wordpress installed with all of the features you need for production ready WordPress under Nginx, MariaDB, and Redis. And cloud-config-le files add support for LetsEncrypt. Otherwise, a self generated certificate is generated that you will need to replace with a certificate from a trusted authority or use a tool like mkcert to generate your own local certificates for local development purposes.

After VM Creation

Mount this folder to your VM or clone the repository and run configuration from the commandline. Update environment variables in the runcmd module to meet your own needs.

multipass mount ../cloud-devops wordpress:/home/ubuntu/cloud-devops

git clone https://github.com/jamfire/multipass-devops.git devops

SSH into your VM and use cloud-init to install your system. You will need to update your public ssh_authorized_key under users and change your username if you would like. The following commands assume a clean install of ubuntu where no other cloud configurations have been applied.

ssh developer@192.168.64.1

sudo cloud-init clean
sudo cloud-init -f ./devops/wp-cloud-config.yml init
sudo cloud-init -f ./devops/wp-cloud-config.yml modules
sudo cloud-init -f ./devops/wp-cloud-config.yml modules -m final

Multipass Domain Mapping

A multipass-hosts.sh bash script has been included with this repository. Running this script will automatically update your /etc/hosts file with your multipass vm's. The script will take the hostname and ip of each of your running multipass vm's and add them to the end of your hosts file.

You will see output similar to this in your hosts file:

### start multipass routing ###

192.168.64.58 wordpress.local
192.168.64.57 moodle.local

### end multipass routing ###
