➡️ Terraform module for Azure Cache for Redis

➡️ Terraform module for Google Memorystore

Versions

• Module tested for Terraform 1.0.1.
• AWS provider version 4.35
• main branch: Provider versions not pinned to keep up with Terraform releases
• tags releases: Tags are pinned with versions (use in your releases)

Usage

Option 1:

terrafrom init
terraform plan -var='teamid=tryme' -var='prjid=project1'
terraform apply -var='teamid=tryme' -var='prjid=project1'
terraform destroy -var='teamid=tryme' -var='prjid=project1'

Note: With this option please take care of remote state storage

Option 2:

Recommended method (stores remote state in remote backend(S3, Azure storage, or Google bucket) using prjid and teamid to create directory structure):

• Create python 3.8+ virtual environment

python3 -m venv <venv name>

• Install package:

pip install tfremote --upgrade

• Set below environment variables:

export TF_AWS_BUCKET=<remote state bucket name>
export TF_AWS_BUCKET_REGION=us-west-2
export TF_AWS_PROFILE=<profile from ~/.ws/credentials>

or

• Set below environment variables:

export TF_AWS_BUCKET=<remote state bucket name>
export TF_AWS_BUCKET_REGION=us-west-2
export AWS_ACCESS_KEY_ID=<aws_access_key_id>
export AWS_SECRET_ACCESS_KEY=<aws_secret_access_key>

• Updated examples directory with required values.

• Run and verify the output before deploying:

tf -c=aws plan -var='teamid=foo' -var='prjid=bar'

• Run below to deploy:

tf -c=aws apply -var='teamid=foo' -var='prjid=bar'

• Run below to destroy:

tf -c=aws destroy -var='teamid=foo' -var='prjid=bar'
