Solution for the DevOps Kata, Kata 1

Solution for the DevOps Kata, Kata 1

• Provisions a server image with Packer and Ansible
• Creates an AWS infra with Terraform

See the denyago/sample-rails-app for a Docker'ised Ruby on Rails app to be deployed into the infra.

Running

Configure

Use a separate profile, if you have multiple accounts. If not, just don't set this option and avoid the environment variable.

aws configure --profile devops-kata

Create a new AMI

cd ami
AWS_PROFILE=devops-kata ./build.sh

...the job will return the image ID. Add it to the variables file (infra.tfvars) on the next step.

Costs may apply! Storing your AMI costs money. If you are experimenting, make sure you de-register AMI and destroy it's snapshot.

Create a new AWS infrastructure

Ensure that you have an SSH key pair in AWS. When you create it, save the name to infra.tfvars:

app_servers_ssh_key_name = "<your SSH key pair here>"
app_server_ami_id = "<your AMI image ID here>"

Plan the changes (not mandatory):

cd terraform
AWS_PROFILE=devops-kata terraform plan -var-file=infra.tfvars

Apply (resources will be created in the cloud):

AWS_PROFILE=devops-kata terraform apply -var-file=infra.tfvars

Costs may apply! Don't forget to destroy, what your are not using:

AWS_PROFILE=devops-kata terraform destroy -var-file=infra.tfvars
