remote_environment

Configuration of a remote execution environment used for building your code.

Environment configuration includes platform properties and a fallback environment, as well as environment-aware options (such as environment variables and search paths) used by Pants to execute processes in this remote environment.

Note that you must also configure remote execution with the global options like remote_execution and remote_execution_address.

To use this environment, map this target's address with a memorable name in [environments-preview].names. You can then consume this environment by specifying the name in the environment field defined on other targets.

Often, it is only necessary to have a single remote_environment target for your repository, but it can be useful to have >1 so that you can set different extra_platform_properties. For example, with some servers, you could use this to configure a different Docker image per environment.

Backend: pants.core

apache_thrift_thrift_search_paths​

Iterable[str] | None
default: None
backend: pants.backend.codegen.thrift.apache.python

Overrides the default value from the option [apache-thrift].thrift_search_paths when this environment target is active.

cache_binary_discovery​

bool
default: False

If true, will cache system binary discovery, e.g. finding Python interpreters.

When safe to do, it is preferable to set this option to True for faster performance by avoiding wasted work. Otherwise, Pants will search for system binaries whenever the Pants daemon is restarted.

However, it is only safe to set this to True if the remote execution environment has a stable environment, e.g. the server will not change versions of installed system binaries. Otherwise, you risk caching results that become stale when the server changes its environment, which may break your builds. With some remote execution servers, you can specify a Docker image to run with via the field extra_platform_properties; if you are able to specify what Docker image to use, and also use a pinned tag of the image, it is likely safe to set this field to true.

description​

str | None
default: None

A human-readable description of the target.

Use pants list --documented :: to see all targets with descriptions.

docker_env_vars​

Iterable[str] | None
default: None
backend: pants.backend.docker

Overrides the default value from the option [docker].env_vars when this environment target is active.

docker_executable_search_paths​

Iterable[str] | None
default: None
backend: pants.backend.docker

Overrides the default value from the option [docker].executable_search_paths when this environment target is active.

extra_platform_properties​

Iterable[str] | None
default: ()

Platform properties to set on remote execution requests.

Format: property=value. Multiple values should be specified as multiple occurrences of this flag.

Pants itself may add additional platform properties.

fallback_environment​

str | None
default: None

The environment to fallback to when remote execution is disabled via the global option --remote-execution.

Must be an environment name from the option [environments-preview].names, the special string __local__ to use the relevant local environment, or the Python value None to error when remote execution is disabled.

Tip: if you are using a Docker image with your remote execution environment (usually enabled by setting the field extra_platform_properties), then it can be useful to fallback to an equivalent docker_image target so that you have a consistent execution environment.
