What courses would you start with first? Are there free ones? Like a good free bootcamp with labs and stuff or do I pay for udemy or pluralsight? Now the more I read though people are saying to start with kodekloud or cs50. Someone also mentioned a place called freecodecamp. submitted by /u/WildFalcon6425 [visit reddit] [comments ..read more

So its my last hope here. We have a school project to make a private cloud with our laptops. So far everything went well, followed the documents and could create instances. The issue is I cant ping 8.8.8.8, host IP and the instances cant ping each other. I have configured everything using the option 1 : provider network Edit : Version I'm using is Antelope Instance IP a (looks like the machine is not getting an IP) Controller IP a Instances Network info Subnet submitted by /u/Zikalol [visit reddit] [comments ..read more

Has anyone attempted deploying multiple regions using Charmed OS? I have a maas controller in each region and juju controller with a separate model for each region (region1, regions2). It seems cross model relations is what I want, but can find very little information online as to how to use this to point the second region and the Keystone in region1. Of course region2 will rely on region1, but will looking DR solution for that later. submitted by /u/Foreign-Wrongdoer806 [visit reddit] [comments ..read more

I am building a small OpenStack cloud in my lab and had a few questions. I want to use OpenStack Ansible for the deployment. I have 5 physical servers each with >128GB and 2 XEON CPUs each with 24 Cores 3 of the 5 servers are currently running VMware ESXI managed by vCenter in a cluster. My questions: I want to use my remaining two servers as Nova compute hosts. Can the other remaining OpenStack services be installed on vm's running in my VMware environment? Would this be acceptable production? What would be a better solution if not? Can I separate OpenStack services and install them on th ..read more

I'm using Openstack Yoga. I created an instance with 400GB of disk, but after 60 retries the volume allocation had failed (now I've changed block_device_allocate_retries to 500 in nova.conf). I later deleted the failing instance but the associated 400GB volume would not be deleted. I tried to manually wipe the volume using commands: cinder reset-state --reset-migration-status VOLUME_ID cinder reset-state --attach-status detached VOLUME_ID cinder delete VOLUME_ID but the volume remained in the "deleting_error" state, so I followed this other procedure to delete the volume directly from the ..read more

There was a similar question asked a while back about images/glance, but this is different enough I thought it warranted its own thread. If I blow away and redeploy openstack and reconnect it to the same ceph cluster, is there a way to get cinder to know about/slurp in those existing volumes in the ceph cluster? I know the obvious way is to export the volume out of ceph, then upload it as a glance image on the new, freshly deployed openstack, done that loads of times before, but that seems silly to download and reupload to ceph essentially, given the volume is already sitting there in the vol ..read more
