All,
Distro provided tomcat6/7/* has caused production issues for few users in the past. Due to this, the ACS deployments are inconsistent with the version/jars of tomcat in use. By allowing exploded war to be shipped, can allow admins to sometimes overwrite cloudstack jars causing production issues. I think moving to a CloudStack uber/fat jar will make it easier to deploy CloudStack in environments and write custom init/systemd scripts and fix cloudstack setup databases/management scripts without assuming the distro we're on. With this discussion thread, I would like to engage with the community if they've any reservations from moving away from tomcat to embedded jetty + fat/uber jar based packaging. Please share your thoughts and comments. On very high level the packaging will provide the following: - A ServerDaemon class that can accept custom location of UI (webapp directory), logging, and other environment options, part of the fatjar. - A config file (xml/yml or otherwise) where you can configure keystore/SSL-certificates, paths (/client), ports, logging etc. - Default libraries/plugin path at /usr/share/cloudstack-management/lib, UI path at /usr/share/cloudstack-management/webapp - A default file (available at /etc/default/cloudstack-management or symlink at /etc/sysconfig etc) where you can specific custom variables, java options, classpath etc. - Refactored init.d/systemd scripts to be commonly used b/w rpm/deb build scripts - A new/improve logrotate file - Logging will be handled by log4j (the same xml/config file you normally use) - Currently we're using jsvc to handle mgmt server process, however we may move to java+systemd completely Marc-Aurèle (ExoScale) and I have collaborated on this problem and we finally have a PR (not complete) where we can show this actually works, please have a look: https://github.com/apache/cloudstack/pull/2226 Once the PR is accepted, we can include a topic page in the 4.11/future release notes docs about upgrading in-place and setting up ssl certs etc. Regards. rohit.ya...@shapeblue.com www.shapeblue.com 53 Chandos Place, Covent Garden, London WC2N 4HSUK @shapeblue
