DevOps Tip - How to use shared terraform plugins by -plugin-dir argument?

Problem

If you executed `terraform init`, you may already have the .terraform in your folder.

Because you may have many terraform repo similar to another, you can use the -plugin-dir to reduce the usage of disk space.

As a shared plugins so that we don’t need many copies of plugins into different locations.

Example

• Here I used my OSX Macbook as a Demo Environment.

  ====================
  cd /build/setupdev/

    sudo mkdir -p  /opt/terraform/terraform.d

mv .terraform/plugins to /opt/terraform/terraform.d/plugins

• Please run the following command to apply it.

  ====================

terraform init -input=false \
-plugin-dir=/opt/terraform/terraform.d/plugins/darwin_amd64
