Environment

Environment image

Do one of the following:

  • To use a Docker image managed by AWS CodeBuild, choose Managed image, and then make selections from Operating system, Runtime(s), Image, and Image version. Make a selection from Environment type if it is available.

  • To use another Docker image, choose Custom image. For Environment type, choose ARM, Linux, Linux GPU, or Windows. If you choose Other registry, for External registry URL, enter the name and tag of the Docker image in Docker Hub, using the format docker repository/docker image name. If you choose Amazon ECR, use Amazon ECR repository and Amazon ECR image to choose the Docker image in your AWS account.

  • To use a private Docker image, choose Custom image. For Environment type, choose ARM, Linux, Linux GPU, or Windows. For Image registry, choose Other registry, and then enter the ARN of the credentials for your private Docker image. The credentials must be created by Secrets Manager. For more information, see What Is AWS Secrets Manager? in the AWS Secrets Manager User Guide.

Privileged

(Optional) Select Privileged only if you plan to use this build project to build Docker images, and the build environment image you chose is not provided by CodeBuild with Docker support. Otherwise, all associated builds that attempt to interact with the Docker daemon fail. You must also start the Docker daemon so that your builds can interact with it. One way to do this is to initialize the Docker daemon in the install phase of your build spec by running the following build commands. Do not run these commands if you chose a build environment image provided by CodeBuild with Docker support.

Note

By default, Docker containers do not allow access to any devices. Privileged mode grants a build project's Docker container access to all devices. For more information, see Runtime Privilege and Linux Capabilities on the Docker Docs website.

- nohup /usr/local/bin/dockerd --host=unix:///var/run/docker.sock --host=tcp://127.0.0.1:2375 --storage-driver=overlay2 - timeout -t 15 sh -c "until docker info; do echo .; sleep 1; done"
Service role

Do one of the following:

  • If you do not have a CodeBuild service role, choose New service role. In Role name, enter a name for the new role.

  • If you have a CodeBuild service role, choose Existing service role. In Role ARN, choose the service role.

Note

When you use the console to create a build project, you can create a CodeBuild service role at the same time. By default, the role works with that build project only. If you use the console to associate this service role with another build project, the role is updated to work with the other build project. A service role can work with up to 10 build projects.

Additional configuration
Timeout

Specify a value between 5 minutes and 480 minutes (8 hours) after which CodeBuild stops the build if it is not complete. If hours and minutes are left blank, the default value of 60 minutes is used.

VPC

If you want CodeBuild to work with your VPC:

  • For VPC, choose the VPC ID that CodeBuild uses.

  • For VPC Subnets, choose the subnets that include resources that CodeBuild uses.

  • For VPC Security groups, choose the security groups that CodeBuild uses to allow access to resources in the VPCs.

For more information, see Use AWS CodeBuild with Amazon Virtual Private Cloud.

Compute

Choose one of the available options.

Environment variables

Enter the name and value, and then choose the type of each environment variable for builds to use.

Note

CodeBuild sets the environment variable for your AWS Region automatically. You must set the following environment variables if you haven't added them to your buildspec.yml:

  • AWS_ACCOUNT_ID

  • IMAGE_REPO_NAME

  • IMAGE_TAG

Console and AWS CLI users can see environment variables. If you have no concerns about the visibility of your environment variable, set the Name and Value fields, and then set Type to Plaintext.

We recommend that you store an environment variable with a sensitive value, such as an AWS access key ID, an AWS secret access key, or a password as a parameter in Amazon EC2 Systems Manager Parameter Store or AWS Secrets Manager.

If you use Amazon EC2 Systems Manager Parameter Store, then for Type, choose Parameter. For Name, enter an identifier for CodeBuild to reference. For Value, enter the parameter's name as stored in Amazon EC2 Systems Manager Parameter Store. Using a parameter named /CodeBuild/dockerLoginPassword as an example, for Type, choose Parameter. For Name, enter LOGIN_PASSWORD. For Value, enter /CodeBuild/dockerLoginPassword.

Important

If you use Amazon EC2 Systems Manager Parameter Store, we recommend that you store parameters with parameter names that start with /CodeBuild/ (for example, /CodeBuild/dockerLoginPassword). You can use the CodeBuild console to create a parameter in Amazon EC2 Systems Manager. Choose Create parameter, and then follow the instructions in the dialog box. (In that dialog box, for KMS key, you can specify the ARN of an AWS KMS key in your account. Amazon EC2 Systems Manager uses this key to encrypt the parameter's value during storage and decrypt it during retrieval.) If you use the CodeBuild console to create a parameter, the console starts the parameter name with /CodeBuild/ as it is being stored. For more information, see Systems Manager Parameter Store and Systems Manager Parameter Store Console Walkthrough in the Amazon EC2 Systems Manager User Guide.

If your build project refers to parameters stored in Amazon EC2 Systems Manager Parameter Store, the build project's service role must allow the ssm:GetParameters action. If you chose New service role earlier, CodeBuild includes this action in the default service role for your build project. However, if you chose Existing service role, you must include this action to your service role separately.

If your build project refers to parameters stored in Amazon EC2 Systems Manager Parameter Store with parameter names that do not start with /CodeBuild/, and you chose New service role, you must update that service role to allow access to parameter names that do not start with /CodeBuild/. This is because that service role allows access only to parameter names that start with /CodeBuild/.

If you choose New service role, the service role includes permission to decrypt all parameters under the /CodeBuild/ namespace in the Amazon EC2 Systems Manager Parameter Store.

Environment variables you set replace existing environment variables. For example, if the Docker image already contains an environment variable named MY_VAR with a value of my_value, and you set an environment variable named MY_VAR with a value of other_value, then my_value is replaced by other_value. Similarly, if the Docker image already contains an environment variable named PATH with a value of /usr/local/sbin:/usr/local/bin, and you set an environment variable named PATH with a value of $PATH:/usr/share/ant/bin, then /usr/local/sbin:/usr/local/bin is replaced by the literal value $PATH:/usr/share/ant/bin.

Do not set any environment variable with a name that begins with CODEBUILD_. This prefix is reserved for internal use.

If an environment variable with the same name is defined in multiple places, the value is determined as follows:

  • The value in the start build operation call takes highest precedence.

  • The value in the build project definition takes next precedence.

  • The value in the buildspec declaration takes lowest precedence.

If you use Secrets Manager, for Type, choose Secrets Manager. For Name, enter an identifier for CodeBuild to reference. For Value, enter a reference-key using the pattern secret-id:json-key:version-stage:version-id. For information, see Secrets Manager reference-key in the buildspec file.

Important

If you use Secrets Manager, we recommend that you store secrets with names that start with /CodeBuild/ (for example, /CodeBuild/dockerLoginPassword). For more information, see What Is AWS Secrets Manager? in the AWS Secrets Manager User Guide.

If your build project refers to secrets stored in Secrets Manager, the build project's service role must allow the secretsmanager:GetSecretValue action. If you chose New service role earlier, CodeBuild includes this action in the default service role for your build project. However, if you chose Existing service role, you must include this action to your service role separately.

If your build project refers to secrets stored in Secrets Manager with secret names that do not start with /CodeBuild/, and you chose New service role, you must update the service role to allow access to secret names that do not start with /CodeBuild/. This is because the service role allows access only to secret names that start with /CodeBuild/.

If you choose New service role, the service role includes permission to decrypt all secrets under the /CodeBuild/ namespace in the Secrets Manager.

Buildspec

Build specifications

Do one of the following:

  • If your source code includes a buildspec file, choose Use a buildspec file. By default, CodeBuild looks for a file named buildspec.yml in the source code root directory. If your buildspec file uses a different name or location, enter its path from the source root in Buildspec name (for example, buildspec-two.yml or configuration/buildspec.yml. If the buildspec file is in an S3 bucket, it must be in the same AWS Region as your build project. Specify the buildspec file using its ARN (for example, arn:aws:s3:::my-codebuild-sample2/buildspec.yml).

  • If your source code does not include a buildspec file, or if you want to run build commands different from the ones specified for the build phase in the buildspec.yml file in the source code's root directory, choose Insert build commands. For Build commands, enter the commands you want to run in the build phase. For multiple commands, separate each command by && (for example, mvn test && mvn package). To run commands in other phases, or if you have a long list of commands for the build phase, add a buildspec.yml file to the source code root directory, add the commands to the file, and then choose Use the buildspec.yml in the source code root directory.

For more information, see the Buildspec reference.

Batch configuration

You can run a group of builds as a single execution. For more information, see Batch builds in AWS CodeBuild.

Define batch configuration

Select to allow batch builds in this project.

Batch service role

Provides the service role for batch builds.

Choose one of the following:

  • If you do not have a batch service role, choose New service role. In Service role, enter a name for the new role.

  • If you have a batch service role, choose Existing service role. In Service role, choose the service role.

Batch builds introduce a new security role in the batch configuration. This new role is required as CodeBuild must be able to call the StartBuild, StopBuild, and RetryBuild actions on your behalf to run builds as part of a batch. Customers should use a new role, and not the same role they use in their build, for two reasons:

  • Giving the build role StartBuild, StopBuild, and RetryBuild permissions would allow a single build to start more builds via the buildspec.

  • CodeBuild batch builds provide restrictions that restrict the number of builds and compute types that can be used for the builds in the batch. If the build role has these permissions, it is possible the builds themselves could bypass these restrictions.

Allowed compute type(s) for batch

Select the compute types allowed for the batch. Select all that apply.

Maximum builds allowed in batch

Enter the maximum number of builds allowed in the batch. If a batch exceeds this limit, the batch will fail.

Batch timeout

Enter the maximum amount of time for the batch build to complete.

Combine artifacts

Select Combine all artifacts from batch into a single location to have all of the artifacts from the batch combined into a single location.

Artifacts

Type

Do one of the following:

  • If you do not want to create any build output artifacts, choose No artifacts. You might want to do this if you're only running build tests or you want to push a Docker image to an Amazon ECR repository.

  • To store the build output in an S3 bucket, choose Amazon S3, and then do the following:

    • If you want to use your project name for the build output ZIP file or folder, leave Name blank. Otherwise, enter the name. (If you want to output a ZIP file, and you want the ZIP file to have a file extension, be sure to include it after the ZIP file name.)

    • Select Enable semantic versioning if you want a name specified in the buildspec file to override any name that is specified in the console. The name in a buildspec file is calculated at build time and uses the Shell command language. For example, you can append a date and time to your artifact name so that it is always unique. Unique artifact names prevent artifacts from being overwritten. For more information, see Buildspec syntax.

    • For Bucket name, choose the name of the output bucket.

    • If you chose Insert build commands earlier in this procedure, then for Output files, enter the locations of the files from the build that you want to put into the build output ZIP file or folder. For multiple locations, separate each location with a comma (for example, appspec.yml, target/my-app.jar). For more information, see the description of files in Buildspec syntax.

    • If you do not want your build artifacts encrypted, select Remove artifacts encryption.

For each secondary set of artifacts you want:

  1. For Artifact identifier, enter a value that is fewer than 128 characters and contains only alphanumeric characters and underscores.

  2. Choose Add artifact.

  3. Follow the previous steps to configure your secondary artifacts.

  4. Choose Save artifact.

Additional configuration
Encryption key

(Optional) Do one of the following:

  • To use the AWS-managed customer managed key (CMK) for Amazon S3 in your account to encrypt the build output artifacts, leave Encryption key blank. This is the default.

  • To use a customer-managed CMK to encrypt the build output artifacts, in Encryption key, enter the ARN of the CMK. Use the format arn:aws:kms:region-ID:account-ID:key/key-ID.

Cache type

For Cache type, choose one of the following:

  • If you do not want to use a cache, choose No cache.

  • If you want to use an Amazon S3 cache, choose Amazon S3, and then do the following:

    • For Bucket, choose the name of the S3 bucket where the cache is stored.

    • (Optional) For Cache path prefix, enter an Amazon S3 path prefix. The Cache path prefix value is similar to a directory name. It makes it possible for you to store the cache under the same directory in a bucket.

      Important

      Do not append a trailing slash (/) to the end of the path prefix.

  • If you want to use a local cache, choose Local, and then choose one or more local cache modes.

    Note

    Docker layer cache mode is available for Linux only. If you choose it, your project must run in privileged mode. The ARM_CONTAINER and LINUX_GPU_CONTAINER environment types and the BUILD_GENERAL1_2XLARGE compute type do not support the use of a local cache.

Using a cache saves considerable build time because reusable pieces of the build environment are stored in the cache and used across builds. For information about specifying a cache in the buildspec file, see Buildspec syntax. For more information about caching, see Build caching in AWS CodeBuild.

Logs

Choose the logs you want to create. You can create Amazon CloudWatch Logs, Amazon S3 logs, or both.

CloudWatch

If you want Amazon CloudWatch Logs logs:

CloudWatch logs

Select CloudWatch logs.

Group name

Enter the name of your Amazon CloudWatch Logs log group.

Stream name

Enter your Amazon CloudWatch Logs log stream name.

S3

If you want Amazon S3 logs:

S3 logs

Select S3 logs.

Bucket

Choose the name of the S3 bucket for your logs.

Path prefix

Enter the prefix for your logs.

Disable S3 log encryption

Select if you do not want your S3 logs encrypted.
