Depot CLI

Official CLI for Depot - you can use the CLI to build Docker images via Depot's remote builder infrastructure.

---

⚡ Depot provides cloud-hosted container builder machines - our builders are quick, running on native hardware. Build caching is fully managed with no extra configuration.

Installation

For Mac, you can install the CLI with Homebrew:

brew install depot/tap/depot

For all other platforms, you can download the binary directly from the latest release.

Quick Start

1. Run depot login to authenticate with your Depot account.
2. cd to your project directory.
3. Run depot init to link the local directory with a Depot project - this will create a depot.json file in the current directory.
4. Run depot build -t repo/image:tag .

Usage

depot bake

Run a Docker build from a HCL, JSON, or Compose file using Depot's remote builder infrastructure. This command accepts all the command line flags as Docker's docker buildx bake command, you can run depot bake --help for the full list.

The bake command needs to know which project id to route the build to. For passing the project id you have three options available to you:

1. Run depot init at the root of your repository and commit the resulting depot.json file
2. Use the --project flag in your depot bake command
3. Set the DEPOT_PROJECT_ID environment variable which will be automatically detected

By default, depot bake will leave the built image in the remote builder cache. If you would like to download the image to your local Docker daemon (for instance, to docker run the result), you can use the --load flag.

Alternatively, to push the image to a remote registry directly from the builder instance, you can use the --push flag.

The bake command allows you to define all of your build targets in a central file, either HCL, JSON, or Compose. You can then pass that file to the bake command and Depot will build all of the target images with all of their options (i.e. platforms, tags, build arguments, etc.).

Example

An example docker-bake.hcl file:

group "default" {
  targets = ["original", "db"]
}

target "original" {
  dockerfile = "Dockerfile"
  platforms = ["linux/amd64", "linux/arm64"]
  tags = ["example/app:test"]
}

target "db" {
  dockerfile = "Dockerfile.db"
  platforms = ["linux/amd64", "linux/arm64"]
  tags = ["example/db:test"]
}

To build all of the images we just need to call bake:

depot bake -f docker-bake.hcl

If you want to build a specific target in the bake file, you can specify it in the bake command:

depot bake -f docker-bake.hcl original

depot build

Runs a Docker build using Depot's remote builder infrastructure. This command accepts all the command line flags as Docker's docker buildx build command, you can run depot build --help for the full list.

The build command needs to know which project id to route the build to. For passing the project id you have three options available to you:

1. Run depot init at the root of your repository and commit the resulting depot.json file
2. Use the --project flag in your depot build command
3. Set the DEPOT_PROJECT_ID environment variable which will be automatically detected

By default, depot build will leave the built image in the remote builder cache. If you would like to download the image to your local Docker daemon (for instance, to docker run the result), you can use the --load flag.

Alternatively, to push the image to a remote registry directly from the builder instance, you can use the --push flag.

Example

# Build remotely
depot build -t repo/image:tag .

# Build remotely, download the container locally
depot build -t repo/image:tag . --load

# Build remotely, push to a registry
depot build -t repo/image:tag . --push

depot cache

Interact with the cache associated with a Depot project. The cache command consists of subcommands for each operation.

depot cache reset

Reset the cache of the Depot project to force a new empty cache volume to be created.

Example

Reset the cache of the current project ID in the root depot.json

depot cache reset .

Reset the cache of a specific project ID

depot cache reset --project 12345678910

depot init

Initialize an existing Depot project in the current directory. The CLI will display an interactive list of your Depot projects for you to choose from, then write a depot.json file in the current directory with the contents {"projectID": "xxxxxxxxxx"}.

Example

depot init

depot login

Authenticates with your Depot account, automatically creating and storing a personal API token on your local machine.

Example

depot login
