Depot Container Builds
Depot Container Builds runs Docker image builds on managed remote infrastructure, with persistent caching and native support for Intel and Arm architectures.
Why it caught my attention
Docker builds can become a surprisingly expensive part of the development cycle, especially when teams repeatedly rebuild the same dependencies. Depot tackles this without requiring a complete CI overhaul. Its shared caching and native multi-architecture builders make an everyday bottleneck worth reconsidering.
What problem does this actually solve?
Depot Container Builds could be worth considering if you recognise any of these challenges.
Slow container builds delay feedback
Remote build machines and reusable cached layers can shorten the wait between code changes and usable images.
Teams repeatedly rebuild identical dependencies
A shared project cache lets developers and CI jobs reuse previously built layers instead of duplicating work.
Building for different processors is cumbersome
Native Intel and Arm builders avoid the emulation often needed when producing images for different processor architectures.
Build infrastructure consumes engineering time
Managed builders reduce the need to provision, maintain and scale dedicated machines for container image builds.
Is this a good fit for you?
A quick way to see if Depot Container Builds is relevant for your situation.
- Your CI pipelines spend substantial time building Docker images.
- Your team frequently rebuilds images with shared dependencies.
- You need container images for both Intel and Arm environments.
- Developers want to offload resource-intensive builds from their machines.
- You want faster builds without replacing your existing CI provider.
- Your container builds are already quick and infrequent.
- Your policies prohibit sending build contexts to externally hosted infrastructure.
How does it work?
In practice, the workflow looks something like this:
Sign up, create a project and associate it with the application or repository whose container images you want to build.
Install the Depot CLI and replace your Docker build command, or configure an integration with your existing CI provider.
Depot transfers the build context to managed BuildKit infrastructure, selecting native builder architectures according to the requested image platforms.
Completed builds populate persistent project caches, allowing subsequent builds to reuse unchanged layers across developers and CI jobs.
Push the completed image to a container registry, save it in Depot Registry or load it into your local Docker environment.
What else should I know?
A few important things to be aware of before you investigate further.
Builds run on remote infrastructure
Your build context is transferred to remote builders. Check data handling, network access and deployment requirements before adoption.
Pricing depends on build usage
Plans include build minutes and cache allowances, with additional charges possible. Compare total costs against your existing build infrastructure.
Caching depends on build structure
Persistent caching helps most when layers remain reusable. Frequently changing dependencies or poorly structured Dockerfiles can limit improvements.
Not a complete CI replacement
Container Builds handles image creation within existing workflows. Depot CI and GitHub Actions Runners are separate product offerings.
