cAdvisor (Container Advisor) provides container users an understanding of the resource usage and performance characteristics of their running containers. It is a running daemon that collects, aggregates, processes, and exports information about running containers. Specifically, for each container it keeps resource isolation parameters, historical resource usage, and histograms of complete historical resource usage. This data is exported by container and machine-wide.
Official cAdvisor releases are built on Linux and exported over a scratch image, this guarantees a small image size.
Each cAdvisor version is tagged. We also have 2 tags for the beta and stable track:
- latest: Latest stable build, this is the latest officially supported releases.
- canary: Images built from HEAD periodically. Potentially unstable!
We also have an Automated Build canary release of cAdvisor which is continuously built from HEAD. This can be found in the google/cadvisor-canary image. It is not recommended for production use due to its size and volatility.
