Agenda/Notes
ThoughtWorks Update
- Bharat presetned on Bahmni
- Using CentOS and yum to install
- yum install openmrs
- yum insatll bahmni-emr
- yum install bahmni-lab
- yum install bahmni-erp
- Ansible
- All install locations are in /opt folder.
- And each component has its own embedded tomcat service.
- Daniel: what are the advantages/disadvantages of this?
- Bharat:
- isolation is a big advantage
- enables easier one-click installation, given different possible configurations
- splitting up the logs
- has made it easier to connect to tomcat via JPDA for debugging
- disadvantage is that the RPMs are bigger
- Apache is used with letsencrypt for automatic SSL config and openmrs/bahmni are reverse proxied through httpd
- Added "Program Enrollment Attributes"
- also built a web service for thi
- will be moved to openmrs-core (when release timeline allows)
- Bahmni blog
- e.g. including monthly "tech reports": https://medium.com/bahmni-blog/december-tech-report-34b70b8a74af#.d20liw8r6
- Soon we'll be publishing the Bahmni roadmap (publicly so everyone can have visibility)
Questions
Is there common code with the multiple embedded tomcats which could be separated into a separate rpm and so the total package size would be smaller.?
- Neflix nebula plugin
- RPM is packaged here: https://github.com/Bahmni/bahmni-package
- In theory, if someone wanted to have the "smallest possible install for their chosen configuration" then they could splice together different commands from the bahmni ansible playboods, and build their own custom RPM, right? (but this is not recommended)
- True
Are the modules bundled in the war file?
- Module omods are available at /opt/openmrs/module
- This document (at the bottom) mentions the paths of various installed files: https://bahmni.atlassian.net/wiki/display/BAH/Install+Bahmni+on+CentOS
- and they are bundled in the bahmni-emr RPM
How do you do upgrades?
- one version of each RPM for each release
- so you would do "yum remove" and "yum install"
- yum update does not work at this time (because of a limitation in the nebula plugin, or yum-gradle)
What about config files?
- Config files are removed if you yum remove
- Config file & database backups can be provided as inputs
- The database stays around (during upgrade) because you haven't removed mysql/pgsql?
- True. The database stays if you yum remove & yum install
Why CentOS (and not Ubuntu)
- CentOS was being used by Bahmni when we started
- Could support deb packages as well, so could support apt-get as well in the future
