add a Docker image with benchmarking utilities#44
Conversation
|
This PR now has two docker images. tidb-sybench (just sysbench with our patch) and tidb-bench (designed to include many benchmarking tools). I have tested tidb-sysbench, and it is now available at gcr.io/pingcap-public/pingcap/tidb-sysbench |

Make the version as an environment variable?

Why run apk add again? A wget to download the oltp_common.lua is enough.

I think it is easy to apk add again if you need it later.

Why add bash in this docker image? The tidb bench script is not included in this image.

I think I agree that these last two can be left out and put in tidb-bench so that this image is just the patched sysbench. It just depends if you want to attach to the container for debugging.

Do we need to make this a separate image?

yes, because we patch sysbench. If we can get our patch upstream it won't really be needed.

Can we just copy this binary to make it work? Is the fio a static binary or dynamically linked binary? From its Dockerfile I don't see any special instruction for static build.

I haven't tested this yet.

Also does this work in alpine? And maybe you can copy from pingcap/go-ycsb directly instead of build the go-ycsb yourself.

I haven't tested this, but it should work. Copying from pingcap/go-ycsb creates additional fragility unless we define a contract for go-ycsb (linux distro, binary location, static build)

The go-ycsb repo already has a Dockerfile. It also uses alpine as builder and final image.

I will adjust this to just add tidb-sysbench which is what I need, and leave a branch with tidb-bench. |

I haven't had a chance to fully test this yet.
Currently it just uses the sysbench patch in this repo, but it would also make sent to build the rest of the directories that are in this repo.
