QUESTION
I'm new to OpenStack and have a basic question about it. Assume that we have 3 Master node (Controller) and 10 Slave node (Compute node) in our cloud. We make 50 VMs (Instances) on the cloud. What will happen if one node (Controller or Compute node) become offline (Failure)? What is the best solution to prevent shutting down a VM if a server get offline?
Best regards
...ANSWER
Answered 2021-Jun-02 at 22:56This question requires more than a short Stackoverflow answer. Here are a few initial thoughts.
When a controller goes offline, the instance itself continues running, but if the failed controller hosts a router, the instance might be cut off from the network. Generally, if the controller has anything that the instance needs, that thing won't be available anymore. There are measures like HA routers that can help in such a case.
When the instance's compute host goes down, the instance doesn't run anymore. You can evacuate instances from a failed compute host, which means that they are rebuilt on different hosts. If an instance's root disk resides on a volume or an ephemeral disk that is shared with other compute hosts, this means a mere instance reboot. If the instance has an ephemeral disk inside the failed host, it must be rebuilt from scratch.
OpenStack has a project named Masakari whose goal is to make instances resilient by redundancy. In short, instance HA. The application keeps running even if an instance crashes.
By the way, master and slave are not correct terminology in this context. Use controller and compute instead.
QUESTION
I'm deploying openstack- stein version on ubuntu pro 18.04 LTS.
I come across these lines when configuring keystone - identity service, as of this article.
Would anybody please explain how to set this following configuration:
...ANSWER
Answered 2021-Apr-27 at 00:25Whether you are root or not has no meaning for the openstack command. The OpenStack admin user has nothing to do with the Linux root user.
You don't need the variables, but your command line becomes very long without them, for example openstack --os-username=admin --os-password=ADMIN_PASS --os-project-name=admin --os-user-domain-name=Default --os-project-domain-name=Default --os-auth-url=http://controller:5000/v3 --os-identity-api-version=3 server list. These variables are the most convenient way to tell the openstack command under which identity it should perform its actions.
How to set them? Type them on the command line, but the most common method is putting them in a file that you source. You can then have several such files for several different identities, such as the admin and demo identities in the linked document, which allows you to quickly switch from one identity to the other.
QUESTION
I'm trying to set up openstack compute nodes that mimics a real node, however never actually sets up the VMs on a physical host.
In the openstack tests, there are usages of fake drivers (defined in nova/virt/fake.py) through a complex system of testing classes.
I wish to get such a node up and running not within a test (meaning, I don't want to use these classes to spawn the compute node), but on an actual VM/container, however, I cannot figure out how to get a compute process to run with this fake hypervisor (or more specifically, one that will be defined by me).
How do I inject this fake driver instead of the real driver in a compute node?
(also, I'm installing OS using devstack (latest))
For more clarification, my goal is to do stress testing of OS, running multiple fake compute nodes, not in all-in-one configuration. The usage of devstack to setup the controller node is for simplifying the process, but the system should be:
- A controller node, running the core services (Nova, Glance, Keystone etc.).
- Multiple compute nodes, using fake hypervisors on different machines.
ANSWER

I'm final student who research and implement Openstack Victoria. When I configure Project: Octavia - Loadbalancer on multi-node - CentOS8, I have a issue. Seem like octavia.amphorae.drivers.haproxy.rest_api_driver couldn't connect to Amphora instance and port 9443 didn't run on my Network Node aka Octavia-API. In controller node, the amphora instance still running nornally. I follow https://www.server-world.info/en/note?os=CentOS_8&p=openstack_victoria4&f=11 to configure my lab. This is my cfg file below, pls help me to figure out. Regards!
I created lb_net in type vxlan and lb-secgroup, when i use command to create lb it still pending-create:
...ANSWER
Answered 2021-May-14 at 18:28Okay, my problem is fixed. The Octavia-api node can't connect to amphorae-instance because they do not match the same network type (node - LAN and amphorae - VXLAN). So, I create a bridge interface at a node to convert vxlan for lan can connect (You can read here at step 7: create a network).

QUESTION
I built the Apache Oozie 5.2.1 from the source code in my MacOS and currently having trouble running it. The ClassNotFoundException indicates a missing class org.apache.hadoop.conf.Configuration but it is available in both libext/ and the Hadoop file system.
I followed the 1st approach given here to copy Hadoop libraries to Oozie binary distro. https://oozie.apache.org/docs/5.2.1/DG_QuickStart.html
I downloaded Hadoop 2.6.0 distro and copied all the jars to libext before running Oozie in addition to other configs, etc as specified in the following blog.
https://www.trytechstuff.com/how-to-setup-apache-hadoop-2-6-0-version-single-node-on-ubuntu-mac/
This is how I installed Hadoop in MacOS. Hadoop 2.6.0 is working fine. http://zhongyaonan.com/hadoop-tutorial/setting-up-hadoop-2-6-on-mac-osx-yosemite.html
This looks pretty basic issue but could not find why the jar/class in libext is not loaded.
- OS: MacOS 10.14.6 (Mojave)
- JAVA: 1.8.0_191
- Hadoop: 2.6.0 (running in the Mac)
ANSWER
Answered 2021-May-09 at 23:25I was able to sort the above issue and few other ClassNotFoundException by copying the following jar files from extlib to lib. Both folder are in oozie_install/oozie-5.2.1.
- libext/hadoop-common-2.6.0.jar
- libext/commons-configuration-1.6.jar
- libext/hadoop-mapreduce-client-core-2.6.0.jar
- libext/hadoop-hdfs-2.6.0.jar
While I am not sure how many more jars need to be moved from libext to lib while I try to run an example workflow/job in oozie. This fix brought up Oozie web site at http://localhost:11000/oozie/
I am also not sure why Oozie doesn't load the libraries in the libext/ folder.

I have installed devstack in my server as per this steps and I was looking for some updated instructions to install kubernates cluster in it. Even though my question is on kubernetes I would like to clarify few points.
- Is Openstack opensource ? or the opensource version is called devstack. Because I was trying to install a production ready environment but everywhere I see examples to install devstack or the one is few years old.
- How to Install Openstack not Devstack
And finally can someone please help me with instruction to install kubernetes on devstack as thats the one I could install now and I guess the instructions would be almost similar.
I know there are posts but almost all of them are few years old so a help would be greatly appreciated.
...ANSWER
Answered 2021-May-09 at 04:35Hoping that it is allowed to reference my own work: I wrote a short series of articles about Kubernetes on Devstack, both Kubernetes from scratch and using OpenStack Magnum.
The document that you used to install OpenStack describes not Devstack, but Microstack.
OpenStack is 100% open-source, yes. See https://www.openstack.org/.
Devstack is one of the many ways to deploy an OpenStack cloud. Its original purpose is to set up a test environment for OpenStack developers, and not so much to be user-friendly, but it is often used for training or proof-of-concept.
There are many other deployment methods: Microstack (easy but not very flexible), Packstack (requires RHEL or Centos), Tripleo (also requires RHEL or Centos and a bit more powerful hardware), Kolla-Ansible, and the best method for learners in my opinion: Manual setup. This list is far from complete.

I used the following helm chart to install Jenkins
https://artifacthub.io/packages/helm/jenkinsci/jenkins
The problem is it does't build docker images, saying there's no docker. Docker was installed on host with sudo apt install docker-ce docker-ce-cli containerd.io
ANSWER
Answered 2021-Apr-08 at 20:25You are running Jenkins itself as a container. Therefore the docker command line application must be present in the container, not the host.
Easiest solution: Use a Jenkins docker image that contains the docker cli already, for example https://hub.docker.com/r/trion/jenkins-docker-client
