Stackoverflow is for programming questions. But your question is about administration.
Please refer to the "IBM Workload Automation" v9.5 "Planning and Installation Guide" for upgrading information, taking care to ensure your starting point is only the most recent fixpack for the v9.5 build.
See https://www.ibm.com/docs/en/workload-automation/9.5.0?topic=installation-upgrading and all related pages in this category, some studying required, careful planning, rehearse in a non-production environment first.
In general consider upgrading only to the "currently supported" versions of IBM software, if you wish to avail of IBM paid support services.
Kubernetes (v1.10.8) installed on my cloud by kismatic (v1.12.0). How I can update kubernetes to the latest version with kubeadm?
With such version difference - we currently have v1.23 (see official supported releases) - I would consider creating the cluster from the beginning.
If this is not possible, you should upgrade them step by step (from version to version). Here you can find guide that will help to upgrade kubeadm clusters.
A link to older versions you can find here, but
NOTE:
Kubernetes v1.19 documentation is no longer actively maintained. The version you are currently viewing is a static snapshot.
However, you have to have in mind that upgrading through so many versions can cause other issues, so I recommend using the first option.
I am newly hired engineer who started working with istio recently. My application is currently running on istio 1.4.3 and having issues when i tried to upgrade to latest using istioctl upgrade.
Below are the steps i tried
1) Verified the versions using istioctl version and saw that control plane and data plane are running on 1.4.3 whereas client version is 1.5.1 (the version i planned to upgrade).
2) Tried istioctl upgrade and seen a message “cannot upgrade because of mismatch of versions in istio components”.
3) As it was my dev environment, i decided to reinstall using istioctl manifest apply --profile default
4) Above step cost me a lot of time, because i lost all the settings related to ingress gateway connected to AWS ALB, instead ingress controller created a classic load balancer which is not part of our previous set-up.
5) I also lost setting related to prometheus, grafana, kiali.
6) Now i am planning upgrade my prod without messing the current settings, please suggest a correct way to upgrade istio to latest version with zero downtime.
what is the best way to do this upgrade, can you point out any link to documentation apart from what is mentioned in istio website ? Help is much appreciated
can you point out any link to documentation apart from what is mentioned in istio website
https://istio.io has the most comprehensive information on the topic.
There are some prerequisites for the Istio upgrade as well.
- Istio version 1.4.4 or higher is installed.
- Your Istio installation was installed using istioctl.
It looks like your Istio version is a tiny step below minimum supported one :)
what is the best way to do this upgrade,
Usually it is recommended to go 1.4 --> 1.5 and only then 1.5 --> 1.6.
I have found the following document that describes an "experimental feature, which is intended for evaluation purposes only".
But the minimal version for it is 1.3.3 or higher, which might do the trick for you.
I hope that helps.
I am trying to get kubernetes 1.3 intalled on my centos7 environment. Have spent a terrifying amount of time looking at every doc/guide/tutorial out there, and unfortunately they are all a combination of outdated versions or missing instructions.
The two biggest issues:
the RPM package is out of date. it pulls down 1.2, not 1.3
which means i need to figure out how to install from source/tar, but i cannot find any good documentation out there on how to do that manually on centos7.
I have gotten it work installing 1.2, but have failed trying to upgrade 1.2 to 1.3 using the 1.3 tar.
Any help would be appreciated!
Centos RPMs are maintained by volunteers, and it seems nobody has volunteered to build a 1.3 RPM. The 1.2 RPM was generated by https://github.com/coolsvap. You could try mailing him and asking him to make a 1.3 rpm.
The way you upgrade depends on which kubernetes guide you followed to setup your kubernetes cluster initially. I'm not sure how it works on Centos guide.
I just found this guide http://kubernetes.io/docs/getting-started-guides/kubeadm/ it mentions Kubernetes 1.4, so since this is a most recent version at the time of writing this post, this might be what you need.
Has any one attempted this before? I would like to know how to upgrade from 4.2 to 4.4 bearing in mind that there are exisiting services on the latter, which I hope will still work on the newly upgraded 4.4.
FuseSource offers migration guides. If you are a FuseSource subscriber then I suggest to use that channel to help with the upgrade.
