Thanks alot Ben this clears most of my doubts related to platform.I have one last question specific to the application i am planning to manage with openshift.i will have a base centos image with all the rpm dependencies of application installed.But for configuring the application it needs to get code from github which i believe its possible.After the code pull it needs to make configuration changes using the code like copying the code to different directories,editing config file with user provided values etc.In our existing environment we use ansible to do this on openstack instance.In short is it possible to do some level of orchestration with openshift on docker images??Thanks again for your helpOn Tue, Jul 21, 2015 at 6:58 PM, Ben Parees <bparees redhat com> wrote:On Tue, Jul 21, 2015 at 2:32 AM, kevin parrikar <kevin parker092 gmail com> wrote:Thanks Ben i will try with
runAsUser.Typestrategy to RunAsAny. Since "docker logs containeri-d" returns nothing.
before i do further experiments with openshift could you clarify some of my doubts regarding openshift v3.1.Is there an admin UI where admin can add users without using "htpasswd" to update "/etc/openshift/openshift-passwd" file manually.There's no web ui way, if there's a CLI way, I defer to david eads (on CC)
2.If i like to create templates similar to the default available templates like mysql/nodejs/cakephp and make it available to all users can i do that.(similar to distro templates in openstack or similar)yes, just create your template.json and run "oc create -f mynewtemplate.json -n openshift" to install the template into the openshift namespace which all users have visibility into. (you will need to perform this operation as cluster admin to be able to write into the openshift namespace)3.In the past i have used openshift online for sometime and there i was able to select Gear with RAM sizing which i dont find it here.(similar to flavors in openstack)v3 is based around a more flexible quota model:
https://docs.openshift.org/latest/dev_guide/limits.html4. I am not able to find SSH key pair creation in this.there is none, you can enter your running containers using "oc exec", authentication is handled by openshift rather than via ssh key pairs:
https://docs.openshift.org/latest/dev_guide/executing_remote_commands.htmlFollowed https://docs.openshift.org/latest/admin_guide/install/overview.html to setup my test environment on 2 vms running on KVM.Ideally PaaS should be simpler than IaaS ,above 4 can be done in openstack and i am still new to openshift.I have worked extensively on openstack and have some knowledge in docker.Thanks,KevinOn Tue, Jul 21, 2015 at 1:48 AM, Ben Parees <bparees redhat com> wrote:can you get the logs from the actual container?
