Very interesting indeed. Thanks for that pointer. However, I think I'm still on the fence about docker (and friends). It looks like a complex solution to independent problems (bundling, jails, snapshots, configuration management). > having said that, i’d like to point out, that florian and myself (the authors > of bsdploy) are very open to using saltstack - bsdploy is designed to be > modular and we already have experimental support for it [2] and the GPL > licence of ansible is turning into a bigger annoyance than expected[3] so we > are motivated to continue along that path. Great, I think you'll like salt although it has a very steep initial learning curve. I'm happy with my choice of saltstack and it appears to have a couple of people contributing FreeBSD improvements reasonably regularly. pkg support is pretty good now and it has limited jail support. The biggest issue I've found with salt is that there is no recommended best-practices way of using it. Its like being given a shed full of wonderful tools and being told to build a house. But at this point I think my problem looks like a thin layer on top of jails rather than something bigger. I still need to try more things and I just found this which looks like a nice way to easily control iocage: https://github.com/bougie/salt-iocage-formula Maybe my workflow is: * destroy jail * create new jail from new template (with new version of app) * use salt to inject the little config files * start jail That means I lose all logs and other things at each upgrade, but with logstash that's less of a problem than it was. On top of that I need a mechanism to create the jail templates, but something manual with FreeBSD pkg might be enough there. If I avoid the iocage 'packaging' thing then it looks like I avoid the unionfs which several people have warned about not being stable.
