AWS::CodeBuild::Project ProjectCache - AWS CloudFormation (original) (raw)

ProjectCache is a property of the AWS CodeBuild Project resource that specifies information about the cache for the build project. If ProjectCache is not specified, then both of its properties default to NO_CACHE.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{
  "CacheNamespace" : String,
  "Location" : String,
  "Modes" : [ String, ... ],
  "Type" : String
}

YAML

  CacheNamespace: String
  Location: String
  Modes: 
    - String
  Type: String

Properties

CacheNamespace

Defines the scope of the cache. You can use this namespace to share a cache across multiple projects. For more information, see Cache sharing between projects in the AWS CodeBuild User Guide.

Required: No

Type: String

Update requires: No interruption

Location

Information about the cache location:

NO_CACHE or LOCAL: This value is ignored.
S3: This is the S3 bucket name/prefix.

Required: No

Type: String

Update requires: No interruption

Modes

An array of strings that specify the local cache modes. You can use one or more local cache modes at the same time. This is only used for LOCAL cache types.

Possible values are:

LOCAL_SOURCE_CACHE

Caches Git metadata for primary and secondary sources. After the cache is created, subsequent builds pull only the change between commits. This mode is a good choice for projects with a clean working directory and a source that is a large Git repository. If you choose this option and your project does not use a Git repository (GitHub, GitHub Enterprise, or Bitbucket), the option is ignored.

LOCAL_DOCKER_LAYER_CACHE

Caches existing Docker layers. This mode is a good choice for projects that build or pull large Docker images. It can prevent the performance issues caused by pulling large Docker images down from the network.

Note

You can use a Docker layer cache in the Linux environment only.
The privileged flag must be set so that your project has the required Docker permissions.
You should consider the security implications before you use a Docker layer cache.

LOCAL_CUSTOM_CACHE

Caches directories you specify in the buildspec file. This mode is a good choice if your build scenario is not suited to one of the other three local cache modes. If you use a custom cache:

Only directories can be specified for caching. You cannot specify individual files.
Symlinks are used to reference cached directories.
Cached directories are linked to your build before it downloads its project sources. Cached items are overridden if a source item has the same name. Directories are specified using cache paths in the buildspec file.

Required: No

Type: Array of String

Update requires: No interruption

Type

The type of cache used by the build project. Valid values include:

NO_CACHE: The build project does not use any cache.
S3: The build project reads and writes from and to S3.
LOCAL: The build project stores a cache locally on a build host that is only available to that build host.

Required: Yes

Type: String

Allowed values: NO_CACHE | S3 | LOCAL

Update requires: No interruption
