If you are running Coder on a VM, this file must be in `/home/coder/aws/credentials`.\n\nTo use another [authentication method](https://registry.terraform.io/providers/hashicorp/aws/latest/docs#authentication), edit the template.\n\n## Required permissions / policy\n\nThe following sample policy allows Coder to create EC2 instances and modify\ninstances provisioned by Coder:\n\n```json\n{\n\t\"Version\": \"2012-10-17\",\n\t\"Statement\": [\n\t\t{\n\t\t\t\"Sid\": \"VisualEditor0\",\n\t\t\t\"Effect\": \"Allow\",\n\t\t\t\"Action\": [\n\t\t\t\t\"ec2:GetDefaultCreditSpecification\",\n\t\t\t\t\"ec2:DescribeIamInstanceProfileAssociations\",\n\t\t\t\t\"ec2:DescribeTags\",\n\t\t\t\t\"ec2:DescribeInstances\",\n\t\t\t\t\"ec2:DescribeInstanceTypes\",\n\t\t\t\t\"ec2:CreateTags\",\n\t\t\t\t\"ec2:RunInstances\",\n\t\t\t\t\"ec2:DescribeInstanceCreditSpecifications\",\n\t\t\t\t\"ec2:DescribeImages\",\n\t\t\t\t\"ec2:ModifyDefaultCreditSpecification\",\n\t\t\t\t\"ec2:DescribeVolumes\"\n\t\t\t],\n\t\t\t\"Resource\": \"*\"\n\t\t},\n\t\t{\n\t\t\t\"Sid\": \"CoderResources\",\n\t\t\t\"Effect\": \"Allow\",\n\t\t\t\"Action\": [\n\t\t\t\t\"ec2:DescribeInstanceAttribute\",\n\t\t\t\t\"ec2:UnmonitorInstances\",\n\t\t\t\t\"ec2:TerminateInstances\",\n\t\t\t\t\"ec2:StartInstances\",\n\t\t\t\t\"ec2:StopInstances\",\n\t\t\t\t\"ec2:DeleteTags\",\n\t\t\t\t\"ec2:MonitorInstances\",\n\t\t\t\t\"ec2:CreateTags\",\n\t\t\t\t\"ec2:RunInstances\",\n\t\t\t\t\"ec2:ModifyInstanceAttribute\",\n\t\t\t\t\"ec2:ModifyInstanceCreditSpecification\"\n\t\t\t],\n\t\t\t\"Resource\": \"arn:aws:ec2:*:*:instance/*\",\n\t\t\t\"Condition\": {\n\t\t\t\t\"StringEquals\": {\n\t\t\t\t\t\"aws:ResourceTag/Coder_Provisioned\": \"true\"\n\t\t\t\t}\n\t\t\t}\n\t\t}\n\t]\n}\n```\n\n## Architecture\n\nThis template provisions the following resources:\n\n- AWS Instance\n\nCoder uses `aws_ec2_instance_state` to start and stop the VM. This example template is fully persistent, meaning the full filesystem is preserved when the workspace restarts. See this [community example](https://github.com/bpmct/coder-templates/tree/main/aws-linux-ephemeral) of an ephemeral AWS instance.\n\n\u003e **Note**\n\u003e This template is designed to be a starting point! Edit the Terraform to extend the template to support your use case.\n\n## Caching\n\nTo speed up your builds, you can use a container registry as a cache.\nWhen creating the template, set the parameter `cache_repo` to a valid Docker repository in the form `host.tld/path/to/repo`.\n\nSee the [Envbuilder Terraform Provider Examples](https://github.com/coder/terraform-provider-envbuilder/blob/main/examples/resources/envbuilder_cached_image/envbuilder_cached_image_resource.tf/) for a more complete example of how the provider works.\n\n\u003e [!NOTE] We recommend using a registry cache with authentication enabled.\n\u003e To allow Envbuilder to authenticate with a registry cache hosted on ECR, specify an IAM instance\n\u003e profile that has read and write access to the given registry. For more information, see the\n\u003e [AWS documentation](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-ec2_instance-profiles.html).\n\u003e\n\u003e Alternatively, you can specify the variable `cache_repo_docker_config_path`\n\u003e with the path to a Docker config `.json` on disk containing valid credentials for the registry.\n\n## code-server\n\n`code-server` is installed via the [`code-server`](https://registry.coder.com/modules/code-server) registry module. For a list of all modules and templates pplease check [Coder Registry](https://registry.coder.com).\n"

To speed up your builds, you can use a container registry as a cache.

When creating the template, set the parameter `cache_repo` to a valid Docker repository in the form `host.tld/path/to/repo`.

See the [Envbuilder Terraform Provider Examples](https://github.com/coder/terraform-provider-envbuilder/blob/main/examples/resources/envbuilder_cached_image/envbuilder_cached_image_resource.tf/) for a more complete example of how the provider works.
