Optimizing Docker Build Performance in Circle CI
Namespace provides high-performance Remote Builders that can significantly speed up your Docker builds in CircleCI workflows.
The easiest way to use Namespace Remote Builders is through the namespacelabs/build
orb, which handles all the configuration automatically.
Access to Namespace
Namespace federates with CircleCI using OpenID Connect to generate short-lived access tokens.
After a one-time setup, your workflows can access Namespace indefinitely, without relying on pre-shared keys which can be more easily compromised:
-
Find your CircleCI Organization ID in Organization Settings > Overview in the CircleCI web application.
-
Email support at support@namespace.so with both your Organization ID and your Namespace workspace ID from the Dashboard.
Using Remote Builders
Add the orb to your CircleCI configuration
orbs:
build: namespacelabs/build@0.2.1
Configure the Namespace Remote Builder environment
steps:
- checkout
- build/setup
Use the Remote Builder
When invoking docker build
, pass namespace
as --builder
to buildx
:
docker buildx build --builder namespace .
