When I try to run any kubectl command including kubectl version, I get a pop-up saying "This app can't run on your PC, To find a version for your PC, check with the software publisher" when this is closed, the terminal shows "access denied"
The weird thing is, when I run the "kubectl version" command in the directory where I have downloaded kubectl.exe, it works fine.
I have even added this path to my PATH variables.
thank you for the answer, #rally
apparently, in my machine, it was an issue of administrative rights during installation. My workplace's IT added the permission and it worked for me.
Adding this answer here so that if anyone else comes across this problem they can try this solution as well.
Not knowing what exactly you downloaded, i would suggest you to delete everying in the folder and follow the instructions for installing kubectl for Windows from here:
https://kubernetes.io/docs/tasks/tools/install-kubectl-windows/
Note: downloading the .exe is not enough. You need a kubeconfig file "config", which contains the configuration to access your cluster.
kubectl looks for this file in a hidden folder under your user profile directory. c:\users<me>.kube.
Just to let you try, i would suggest you to activate Kubernetes in your Docker-Desktop installation. I guess you have this installed. If not install it from the Dockersite. https://www.docker.com/products/docker-desktop/
Activating Kubernetes inside Docker-desktop, will install also kubectl and save the config in the .kube folder.
After the installation finished, in a new terminal:
kubectl get node
You should see the 1 node in the kubernetes-docker-desktop cluster.
Now if you want to access another cluster, you need the kubeconfig-file for that cluster. If you have it, just rename the config in the .kube folder (to not loose it) and put the other config inside.
If the new config file is correct you should be able to access that cluster.
The config file can be structured to hold more than one cluster configuration and you can switch between them using a so called context.
Here you can get the information how to do that, according to your needs:
https://kubernetes.io/docs/tasks/access-application-cluster/configure-access-multiple-clusters/
Hope this can help you, starting with KUbernetes.

I was getting this windows service error due to a recent Java update on my local machine.
I was finally able to resolve it by following the steps below:
Go to 'System Environment Variables'
Verify 'JAVA_HOME' is pointing to the correct location. If not, change it.
C:\Program Files\Java\jdk-13.0.1
Go to the 'bin' folder for elastic-search-7.4.2 and run below commands to remove and reinstall the service.
C:\elasticsearch-7.4.2\bin elasticsearch-service.bat remove
C:\elasticsearch-7.4.2\bin elasticsearch-service.bat install
I am new here and i will try to explain my question kindly ignore any mistakes.
I am using git version git-2.8.2
It worked fine for one day then this problem occurs.
I am using gcloud repository.
First I tried gcloud clone command then this error occurs
Then to make sure git is there I tired git command then this error occurs
Then I double check by opening git Bash but same error was there too.
I tried reinstalling changing directory. but nothing works.
I face the same problem after I try to avoid memory leak in Windows 10. If you happened to change the regedit like me, just type regedit in the search then go to
HKEY_LOCAL_MACHINE -> SYSTEM -> ControlSet001 -> Services -> Null
change the value of Start to 1.
I accidentally bumped into the same problem when I was sorting out the services running on my computer with Windows 10.
fatal: open /dev/null or dup failed: No such file or directory
The reason was that I deleted the service named 'Null' that had no description as I thought that was a virus service.
Thus, when I found my git unable to operate, I reckoned the deleted service.
According to a solution provided on some site I tried to run the service again using cmd.exe
sc config Null start= system
sc start Null
but it said the service hadn't been existed in the list.
Thankfully, there are some kind folks who shares the information of the default services running on Windows 10 and the description necessary for the successful bringing back the service.
So as to get the service back in the list:
press Win + R
type regedit
go to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services section
Create Null folder and all the params it needs.
Restart your computer.
Now you got your Null service back and your git back as well.
Hope this helps.
I solved my problem accidentally. I would like to share it with everyone.
It was not a problem of git or gcloud or source tree.
Actually I have forcefully stooped windows update from installing which causes this problem.
Now when I install windows updates again this problem is fixed now.
Maybe this helps someone.
the similar situation in chrooted linux tree is fixable following way:
cd inside the folder where you are preparing the chroot dir, then
mount -o bind /dev dev/
then only chroot inside
I had this weird bug just now. I went back a dir and tried git init, it worked there.
I re-ran zsh and tried again in the dir it errored in originally and it worked. shrugs
After updating macOS to Mojave (10.14.4), my Mac was restarted and upon opening Jenkins (at localhost:8080) it appeared that I've lost all my jobs and the entire system configurations.
There was only 1 user (admin) defined in my installation and my usual password was deemed invalid, when I tried to log back in. So, I tried entering another password I normally used and it was accepted. I then found that all my jobs and configs have disappeared. It looked as if I've just started Jenkins for the first time.
Looking through here on StackOverFlow, there were suggestions to check the JENKINS_HOME variable to find out where the jobs are saved on the disk, but when I typed export $JENKINS_HOME I just get an empty response. So, it looks like I've never configured it during set up.
I then dig through the hard drive and found the folders matching the names of the jobs I created under ~/.jenkins/workspace. However, the contents of all the folders are empty. I was expecting to see the usual files, e.g. build.xml, config.xml, etc.
I then did a global search for build.xml and config.xml on Mac Finder it turned up nothing.
Any idea where my jobs went and what could have caused all the contents of the folders of the jobs to be empty?
You can find your Jenkins installation directory in "Manage Jenkins" -> "configure System" --> "Home directory". Find what was the Jenkins home before you restart MAC. It looks like your home directory is either deleted by you or you are pointing to new folder now. Set it to earlier folder.
If can help,
I'm having a similar problem.
The curious part is about the new directory after the service restart ".jenkins" directory inside :
'/var/root/'.
And now, the password that Jenkins request me is not from
'/Users/username/.jenkins/secrets/initialAdministratorPassword' but from the newst one with same path pattern.

I am trying to debug an application I have deployed to google cloud app engine. Reading the docs, I figured out that in order to do so I have to enter the debug mode using
gcloud app --project [Project ID] instances enable-debug
afterwards I am able to SSH into my instance and access root. Now I would like to edit some of the files. However, trying to use vim or nano does not seem to work.
Is there a way to edit those files without re-deploying the entire app?
Once you SSH into the App Engine instance and open a shell into the Docker container, you'll need to download the package list before installing nano or vim:
apt-get update && apt-get install nano
Then you can edit your app's files (which are in /app):
nano composer.json
The deployed app runs live code. It is not generally feasible to edit it. Moreover, changes made to the running container are not permanent; in fact they and are lost at the first re-start.
You may find some information on the Debugging an Instance page.
Unrelated to the above, an actual command-line editor is offered in the cloud shell.
I am trying openshift DIY cartridge. I use a windows system to manage the server from command line. I managed to run a simple html5 website. I have deleted the testrubyserver.ruby file from the webpage folder for test purposed and then added it again to my webfolder. Now i have 503 error. No restart, no stop, no start helps. I am stuck in 503. Does anyone know what to do? How can I make the testrubyserver.ruby run again?
Solved my problem. I checked the log file in the folder: app-root / logs. There I found out that
nohup: failed to run command `/..//testrubyserver.rb': Permission denied
I change in filezilla the permissions for the file from rw to rwx to execute it. Restarted the server and then it worked.
I do not know if this is the right approach. At least it makes my app running again.
