This is a group for people interested in Amazon Web Services. Anyone can participate, ranging from AWS evangelists to the curious. The main focus of the group is to build up a community around AWS with socializing and talks on topics like innovations, development and possibilities. Having trouble with a stack? Maybe you'll meet someone with a solution or an approach that you haven't already tried.
Talk was given by Anton Babenko on DevOps Norway Meetup 14th of December 2015.
Install Terraform - https://www.terraform.io/intro/getting-started/install.html
Install AWS CLI - brew update && brew install awscli (on Mac)
Get AWS IAM access and secret keys from AWS console and export them like this:
export AWS_ACCESS_KEY_ID="something_here"
export AWS_SECRET_ACCESS_KEY="something_secret_here"
export TF_VAR_aws_access_key=$AWS_ACCESS_KEY_ID
export TF_VAR_aws_secret_key=$AWS_SECRET_ACCESS_KEY
Let's deploy demo application and work with AWS infrastructure as code using Terraform.
Terraform remote state is configured using S3.
2 projects:
- web (ELB,ASG,LC)
- shared-aws (VPC,SN) 1 environment:
- production 1 region:
- eu-west-1
If you run ./terraform.sh heavy production plan-destroy it will raise cycle error like:
Error running plan: 1 error(s) occurred:
* Cycle: aws_security_group.elb, aws_security_group.elb (destroy), aws_iam_instance_profile.default (destroy), aws_iam_role.default (destroy), aws_iam_role.default, aws_iam_instance_profile.default, aws_security_group.web_server, aws_launch_configuration.heavy, aws_launch_configuration.heavy (destroy), aws_security_group.web_server (destroy), output.configuration, aws_elb.heavy (destroy), aws_autoscaling_group.heavy (destroy), terraform_remote_state.shared (destroy), terraform_remote_state.shared, aws_elb.heavy, aws_autoscaling_group.heavy
It happens because resource terraform_remote_state.shared does not have lifecycle event defined, so we should destroy all except it:
cd projects/heavy
terraform destroy -var-file=production.tfvars -var-file=terraform.tfvars -var 'environment=production' \
-target=aws_iam_instance_profile.default \
-target=aws_elb.heavy \
-target=aws_security_group.web_server \
-target=template_file.heavy_user_data \
-target=aws_iam_role.default \
-target=aws_security_group.elbCreated and maintained by Anton Babenko.
