Pumba is a chaos testing and network emulation tool for Docker. Pumba can kill, stop, remove or pause Docker containers. Pumba can also emulate networks and simulate different network failures such as delays, packet loss and bandwidth rate limits. Pumba uses the tc tool for network emulation which means it needs to be available in our containers or we need to run Pumba in a sidecar container with tc. Pumba is particularly useful when we want to run some automated chaos tests against a distributed system running on a bunch of containers locally or in the build pipeline.
