I have a Mac with Apple Silicon (M1) and I have minikube installed. The installation was done following https://medium.com/#seohee.sophie.kwon/how-to-run-a-minikube-on-apple-silicon-m1-8373c248d669 by executing:
curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-darwin-arm64
sudo install minikube-darwin-arm64 /usr/local/bin/minikube
How do I remove minikube?
Have you tried to follow any online material to delete Minikube?? Test if this works for you and let me know if you face any issues.
Try using the below command :
minikube stop; minikube delete &&
docker stop $(docker ps -aq) &&
rm -rf ~/.kube ~/.minikube &&
sudo rm -rf /usr/local/bin/localkube /usr/local/bin/minikube &&
launchctl stop '*kubelet*.mount' &&
launchctl stop localkube.service &&
launchctl disable localkube.service &&
sudo rm -rf /etc/kubernetes/ &&
docker system prune -af --volumes
Reference used: Delete minikube on Mac
minikube stop; minikube delete
docker stop $(docker ps -aq)
rm -r ~/.kube ~/.minikube
sudo rm /usr/local/bin/localkube /usr/local/bin/minikube
systemctl stop '*kubelet*.mount'
sudo rm -rf /etc/kubernetes/
docker system prune -af --volumes

I am deploying Jenkins Using GitHub Action Runner using Skaffold.
While the Skaffold is installed over the default image of GitHub Runner
The pod is restarting due to crash loop back off error and causing it to restart.
I am not sure why it is happening.
When I am deploying runner over Google Kubernetes Engine my runner is failing because of following error:
'''A runner exists with the same name

I am not sure what exactly is causing this issue.
We created mongodb on aws linux 2. We want seperate volume for logs, journal & some database. For this we enable 'directoryPerDB' in mongodb configuration.
Here's the mount setup we did
sudo mkfs.xfs -L mongodata /dev/sdf
sudo mkfs.xfs -L mongojournal /dev/sdg
sudo mkfs.xfs -L mongolog /dev/sdh
sudo mkfs.xfs -L sampledb /dev/sdi

Also updated in etc/fstab
its working fine for some time. But after few hours my datbase symboli link get removed automatically from system. I don't know how.
Please advice.
I am installing Minikube on Ubuntu 16.04 LTS (instructions available below). It is working fine when I run each command manually. However, if I put these in a script file install.sh it will fail at the last step giving me an error:
Error

Retrying.

An error has occurred. Would you like to opt in to sending anonymized crash

To opt out of these messages, run the command:

sudo rm -rf .minikube/
#Install minikube. Make sure to check for latest version (e.g. current version is 0.28.0)

sudo apt install -y libvirt-bin qemu-kvm
sudo usermod -a -G libvirtd $(whoami)
#Check to ensure libvirtd service is running.
systemctl status libvirtd
minikube start --vm-driver kvm2
Also, when the script fails if I re-run the following command I get the minikube working fine. Just don't know why it fails originally when running within the script.
sudo rm -rf .minikube/
minikube start --vm-driver kvm2
If you're running this script not for the first time, sudo rm -rf .minikube/ will not be enough.
You should also run the below command:
minikube delete
And, just in case, add a shebang to the top of the script:
#!/bin/bash
Having challenges running Eclipse Che multiuser mode on Google Cloud computer engine instance.

Documented fix doesn't work, :/data is already mounted to read/writable directory.
Probably Google Cloud overrides file system permissions somehow. Have you tried mounting different dirs into :/data?
I've tested your command and it works in my case by using a GCP instance with Debian 9 and docker 17.12, here is the steps that I've followed:
1) install docker
$ sudo apt-get install apt-transport-https ca-certificates curl gnupg2 software-properties-common
$ curl -fsSL https://download.docker.com/linux/$(. /etc/os-release; echo "$ID")/gpg | sudo apt-key add -
$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/$(. /etc/os-release; echo "$ID") $(lsb_release -cs) stable"
$ sudo apt-get install docker-ce
2) run che, I've used as a directory the /tmp, I recommend you to create another directory to store the files
$ sudo docker run -it -e CHE_MULTIUSER=true -e CHE_HOST=INTERNAL-IP -v /var/run/docker.sock:/var/run/docker.sock -v /DIRECTORY_WITH_PERMISSIONS:/data eclipse/che start
I have already asked this question on serverfault.com. I am asking it here too as I see different set of questions in these 2 sites (it appears like they have different databases).
I have been trying to build an OS image from Fedora unsuccessfully to start the following:
Systemd
SSHD
RabbitMQ
MongoDB
I can get the first 3 (Systemd, SSHD and RabbitMQ-Server) to work. I can also get MongoDB to work within the container. However, I cannot get MongoDB to work along with other 3 services.
In addition, IP address doesn't show up when I try to "dockerize" MongoDB.
Am I missing something in the Dockerfile?
Here is my dockerfile:

Docker Commands used to build are:
(1) docker build -t rabbitmq_mongo_heisenbug .
(2) docker run --privileged -d -e 'container=docker' -v /sys/fs/cgroup:/sys/fs/cgroup:ro -p 29022:22 -p 29672:15672 -p 29017:27017 rabbitmq_mongo_heisenbug
or.. (3) docker run --privileged -ti -e 'container=docker' -v /sys/fs/cgroup:/sys/fs/cgroup:ro -p 29022:22 -p 29672:15672 -p 29017:27017 rabbitmq_mongo_heisenbug
You are using both ENTRYPOINT and CMD in your Dockerfile. This means, that docker will run /usr/bin/mongod with default parameter /usr/sbin/init. I'm pretty sure this is not what you want.
Docker will run as long as the command you specified is running. I'm not sure about /usr/bin/mongod, but if it runs in daemon mode (that is, spawn a process and return), then the container will stop running right away. The spawned processes will be terminated. The same is true for /usr/sbin/init or for any other command you specify. You can write a small shell script, which spawns the processes and runs one in the foreground, or you can use runit, or some similar tool.
Also, you probably don't need to run sshd in your container. See here why.
