Builds
Documentation of Apify actors - building your actor.
Before the actor can be run, it first needs to be built. The build effectively creates a snapshot of a specific version of the actor's settings such as the Source code and Environment variables, and creates a Docker image that contains everything the actor needs for its run, including necessary NPM packages, web browsers, etc.
Each build is assigned a unique build number of the form MAJOR.MINOR.BUILD (e.g. 1.2.345), where MAJOR.MINOR corresponds to the actor version number (see Versioning) and BUILD is an automatically-incremented number starting at 1.
By default, the build has a timeout of 300 seconds and consumes 1024 MB of memory from the user's memory limit. See the Resource limits section for more details.
Tags
When running the actor, the caller needs to specify which actor build should actually be used. To simplify this process, the builds can be associated with a tag such latest or beta, which can be used instead of the version number when running the actor. The tags are unique - only one build can be associated with a specific tag.
To set a tag for builds of a specific actor version, set the Build tag property. Whenever a new build of the version is successfully finished, it is automatically assigned the tag. By default, the builds are set the latest tag.
Cache
By default, the build process pulls latest copies of all necessary Docker images and builds each new layer of Docker image from scratch. To speedup the builds triggered via API you can add useCache=1 parameter. See API reference for more details.
Lifecycle
Each build starts with the initial status READY and goes through one or more transitional statuses to one of the terminal statuses.
