mysql - Could number of docker containers be limited by file IO inside containers? -


i trying stuff many lamp stack containers inside docker possible running wordpress. according many sources possible stuff on 500 containers on docker server, example:

however, discuss empty docker containers , not lamp stack ones (apache+mysql).

i have managed stuff 120 containers running wordpress , don't see siginifcant issue ram or cpu. should able fit more performance goes downhill in response times after point.

a colleague has mentioned mysql performs significant i/o operations cause issues file descriptors / open file limits / , fs.io.max.nr .

could case? number of open files of each containers limits total number of containers?
