See Cloud builders documentation for extra.
Construct Config Information
Construct config recordsdata outline the construct steps and their execution order. They’re sometimes written in YAML or JSON format. Learn extra at Create a build configuration file.
Artifacts and Storage
- Artifacts: These are recordsdata produced by the construct course of, resembling compiled binaries, Docker photos, or take a look at outcomes. Artifacts may be saved and retrieved for additional use or deployment.
- Storage: Cloud Construct can retailer artifacts in Google Cloud Storage (GCS) or Google Container Registry (GCR). GCS is used to retailer basic recordsdata, whereas GCR is particularly used for Docker photos.
Optimization Methods for Cloud Construct CI/CD
Though Cloud Construct gives many key ideas and tremendously simplifies CI/CD, we nonetheless want just a few optimization strategies to attain excellence on this space.Â
Allow us to categorize the optimization strategies into the next:
Velocity and Effectivity
We are going to discover the weather that improve the velocity and effectivity of the CI/CD pipelines.
Caching
Make the most of caching to retailer and reuse beforehand constructed artifacts or dependencies, lowering construct instances.
- Docker layer caching: Cache Docker picture layers to keep away from rebuilding unchanged layers.
