You are free to \nconfigure credentials however you like as long as an access key ID and secret\naccess key are available. These instructions utilise \n[aws-vault](https://github.com/99designs/aws-vault) which makes credential\nmanagement easy and secure.\n\nTo provision module infrastructure, run tests and then destroy that \ninfrastructure, execute:\n\n```bash\naws-vault exec \u003cprofile\u003e -- ./go\n```\n\nTo provision the module prerequisites:\n\n```bash\naws-vault exec \u003cprofile\u003e -- ./go deployment:prerequisites:provision[\u003cdeployment_identifier\u003e]\n```\n\nTo provision the module contents:\n\n```bash\naws-vault exec \u003cprofile\u003e -- ./go deployment:root:provision[\u003cdeployment_identifier\u003e]\n```\n\nTo destroy the module contents:\n\n```bash\naws-vault exec \u003cprofile\u003e -- ./go deployment:root:destroy[\u003cdeployment_identifier\u003e]\n```\n\nTo destroy the module prerequisites:\n\n```bash\naws-vault exec \u003cprofile\u003e -- ./go deployment:prerequisites:destroy[\u003cdeployment_identifier\u003e]\n```\n\nConfiguration parameters can be overridden via environment variables:\n\n```bash\nDEPLOYMENT_IDENTIFIER=testing aws-vault exec \u003cprofile\u003e -- ./go\n```\n\nWhen a deployment identifier is provided via an environment variable, \ninfrastructure will not be destroyed at the end of test execution. This can\nbe useful during development to avoid lengthy provision and destroy cycles.\n\nBy default, providers will be downloaded for each terraform execution. To\ncache providers between calls:\n\n```bash\nTF_PLUGIN_CACHE_DIR=\"$HOME/.terraform.d/plugin-cache\" aws-vault exec \u003cprofile\u003e -- ./go\n```\n\n### Common Tasks\n\n#### Generating an SSH key pair\n\nTo generate an SSH key pair:\n\n```\nssh-keygen -m PEM -t rsa -b 4096 -C integration-test@example.com -N '' -f config/secrets/keys/bastion/ssh\n```\n\n#### Generating a self-signed certificate\n\nTo generate a self signed certificate:\n```\nopenssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365\n```\n\nTo decrypt the resulting key:\n\n```\nopenssl rsa -in key.pem -out ssl.key\n```\n\n#### Managing CircleCI keys\n\nTo encrypt a GPG key for use by CircleCI:\n\n```bash\nopenssl aes-256-cbc \\\n  -e \\\n  -md sha1 \\\n  -in ./config/secrets/ci/gpg.private \\\n  -out ./.circleci/gpg.private.enc \\\n  -k \"\u003cpassphrase\u003e\"\n```\n\nTo check decryption is working correctly:\n\n```bash\nopenssl aes-256-cbc \\\n  -d \\\n  -md sha1 \\\n  -in ./.circleci/gpg.private.enc \\\n  -k \"\u003cpassphrase\u003e\"\n```\n\nContributing\n------------\n\nBug reports and pull requests are welcome on GitHub at \nhttps://github.com/infrablocks/terraform-aws-lambda-cloudwatch-events-trigger. \nThis project is intended to be a safe, welcoming space for collaboration, and \ncontributors are expected to adhere to the \n[Contributor Covenant](http://contributor-covenant.org) code of conduct.\n\nLicense\n-------\n\nThe library is available as open source under the terms of the \n[MIT License](http://opensource.org/licenses/MIT).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Finfrablocks%2Fterraform-aws-lambda-cloudwatch-events-trigger","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Finfrablocks%2Fterraform-aws-lambda-cloudwatch-events-trigger","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Finfrablocks%2Fterraform-aws-lambda-cloudwatch-events-trigger/lists"}
