- To run terraform on your local system for your AWS, you will need to first configure AWS on your local system.
- Create a folder .aws/credential and store the AWS credential details at C:\Users\<yourhome folder>\.aws
- You can do the above also through AWS command line > aws configure
- You can define credentials in four different ways,
- Static
- Environment Variable
- Shared Credential file
- EC2 Role
- Static – it is basic method, we directly hard code the credentials in the .tf file provider section.
- Environment Variable – Run the below command for windows machine, for Linux system use export commands.
- Once configured the environmental variables, you can all the keys through provider sections.
- Shared Credential files – You can access the credential files created using aws configure command. The file is by default at location $HOME/.aws/credentials. You can call the shared file like below in the provider section.
- EC2 Role – If running under EC2, then you can directly create and assign role to EC2, this avoids use of hard coded credentials.
- Assume role – We can provide role ARN, terraform will attempt this role. You can call the role ARN in provider section.
