Learn how to write the main Actor config in the .actor/actor.json file.

The main Actor config should live in the .actor/actor.json file in the Actor's root directory. This file associates your local development project with an Actor on the Apify platform. It contains information such as Actor name, version, build tag, and environment variables. Make sure you commit this file to the Git repository.

For example, the .actor/actor.json file can look like this:

"actorSpecification": 1, // always 1
"name": "name-of-my-scraper",
"version": "0.0",
"buildTag": "latest",
"minMemoryMbytes": 256,
"maxMemoryMbytes": 4096,
"environmentVariables": {
"MYSQL_USER": "my_username",
"MYSQL_PASSWORD": "@mySecretPassword"
"dockerfile": "./Dockerfile",
"readme": "./",
"input": "./input_schema.json",
"storages": {
"dataset": "./dataset_schema.json",


Note that actor name, version, buildTag, and environmentVariables are currently only used when you deploy your actor using Apify CLI and not when deployed, for example, via GitHub integration. There it serves for informative purposes only. This is suspected to change in the future.

actorSpecificationRequiredWe are at a version 1 which is the only one available so this must be set to 1.
nameRequiredName of the Actor.
versionRequiredActor version in the form [Number].[Number], i.e. for example 0.0, 0.1, 2.3, ...
buildTagOptionalThe tag name applied for the successful build of the Actor. Defaults to latest. For more information see the builds section.
environmentVariablesOptionalA map of environment variables used during the local development that will be also applied to Actor at Apify platform. For more see the environment variables section of Apify CLI documentation.
dockerfileOptionalIf you specify the path to your Docker file under the dockerfile field, this file will be used for actor builds on the platform. If not specified, the system will look for Docker files at .actor/Dockerfile and Dockerfile, in this order of preference. For more see the Dockerfile section.
dockerContextDirOptionalSpecifies the path to the directory used as the Docker context when building the Actor. The path is relative to the location of the actor.json file. Useful for having a monorepo with multiple Actors. See Actor monorepos for more details.
readmeOptionalIf you specify the path to your README file under the readme field, the README at this path will be used on the platform. If not specified, README at .actor/ or will be used, in this order of preference. See our Apify Academy article on writing a quality README files.
inputOptionalYou can embed your input schema object directly in actor.json under the input field. Alternatively, you can provide a path to a custom input schema. If not provided, the input schema at .actor/INPUT_SCHEMA.json or INPUT_SCHEMA.json is used, in this order of preference.
storages.datasetOptionalYou can define the schema of the items in your dataset under the storages.dataset field. This can be either an embedded object or a path to a JSON schema file. Read more about Actor output schemas.
minMemoryMbytesOptionalSpecifies the minimum amount of memory in megabytes that an Actor requires to run. Requires an integer value. If both minMemoryMbytes and maxMemoryMbytes are set, then minMemoryMbytes must be the same or lower than maxMemoryMbytes.
maxMemoryMbytesOptionalSpecifies the maximum amount of memory in megabytes that an Actor requires to run. It can be used to control the costs of run, especially when developing pay per result actors. Requires an integer value.
