Total container cap of 0 reached, not provisioning

[kristoflemmens]

Setting for container cap says 0 (unlimited) but the plugin won't provision. When I set the container cap to 5 or something else the plugin starts with provisioning.

So I found the problem myself by browsing the code. The container cap value has to be empty to have unlimited hosts. The documentation at https://wiki.jenkins-ci.org/display/JENKINS/Docker+Plugin says that 0 is unlimited

Just hit upon this as well. What the documentation at https://wiki.jenkins-ci.org/display/JENKINS/Docker+Plugin says:

Container Cap: The maximum number of containers that this provider is allowed to have running, defaults to blank which disables the limit

used to be true, but changed in https://github.com/jenkinsci/docker-plugin/commit/bde53df15d84e746dba3a40fcaa050bf60260ab1 (by @KostyaSha) so that a blank entry is understood as zero, and sets the limit to zero. It's not clear whether the loss of that functionality was deliberate, so I suggest reopening this issue until someone with a broader view can decide whether to fix the documentation or the code.

edit: upon re-reading and noticing the date of this issue, I realized mine was different. I'll go and open another one.
