Powerful CI/CD for Docker and Kubernetes

Compose Docker images to match your environment

Use the exact same environment for development, testing, CI and production.

Public or private Docker images

Pull any public image or securely authenticate with a container registry to run jobs in your own private images.

Supports all common registries

Supports most common registries including Docker Hub, Google Container Registry, Amazon ECR and Azure Container Registry.

7× faster Docker builds

Semaphore builds container images more than 7× faster comparing to typical registries, thanks to the power of bare metal machines.

Complete flexibility

Use the full power of the Docker CLI to build your images in a clean Linux VM, then continuously deploy or manually promote to any registry.

For your convenience, Semaphore comes with a repository of pre-built images hosted on the Semaphore Container Registry. Use these images in your Semaphore environment without any restrictions or limits.

Enterprise-grade release

Deploy a canary release to production from master branch. Deliver an on-demand staging version from a development branch. Semaphore lets you deploy any known good version of your app through as many delivery workflows as you need.

Works with any cloud

Semaphore can deliver your applications to AWS, DigitalOcean, Google Cloud or Microsoft Azure Kubernetes engines. You can also deploy to your own Kubernetes cluster, AWS ECS, Docker Swarm, or any other host that can run Docker containers.

Monitor your deployments

Manage credentials with secrets and integrate security scanners in your pipelines. Configure custom Slack notifications to keep your team in the loop. Set up custom dashboards to see what’s deployed and if everything is up and running.
