Il faut tout d'abord installer Docker :
$ sudo apt update $ sudo apt install apt-transport-https ca-certificates software-properties-common curl $ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - OK $ sudo add-apt-repository \ "deb [arch=armhf] https://download.docker.com/linux/ubuntu \ $(lsb_release -cs) \ stable" $ sudo apt update $ sudo apt install docker-ce $ docker --version Docker version 18.06.1-ce, build e68fc7a
Configurer le service :
$ sudo systemctl enable docker Synchronizing state of docker.service with SysV service script with /lib/systemd/systemd-sysv-install. Executing: /lib/systemd/systemd-sysv-install enable docker $ sudo systemctl start docker $ sudo systemctl status docker ● docker.service - Docker Application Container Engine Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled) Active: active (running) since Thu 2018-10-25 17:03:35 CEST; 1s ago Docs: https://docs.docker.com Main PID: 24001 (dockerd) Tasks: 42 CGroup: /system.slice/docker.service ├─24001 /usr/bin/dockerd -H fd:// └─24025 docker-containerd --config /var/run/docker/containerd/containerd.toml (...)
Il faut aussi installer kubectl :
$ curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add - OK $ echo "deb http://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee -a /etc/apt/sources.list.d/kubernetes.list deb http://apt.kubernetes.io/ kubernetes-xenial main $ sudo apt update $ sudo apt-get install -y kubectl
$ curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 \ && sudo install minikube-linux-amd64 /usr/local/bin/minikube % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 40.3M 100 40.3M 0 0 646k 0 0:01:03 0:01:03 --:--:-- 674k
Si on a déjà une configuration kubectl, ça coince :

J'ai eu une autre erreur où il me dit de faire un minikube delete suivi d'un minikube start (et où il se plaint déjà d'un problème de permissions…

J'essaye de faire le minikube delete comme conseillé.
$ minikube delete Deleting local Kubernetes cluster... Errors occurred deleting machine: Error deleting host: minikube: Error loading host from store: open /home/simon/.minikube/machines/minikube/config.json: permission denied
Encore un problème de permissions… C'est quoi les permissions sur ce dossier ?
$ ls -al /home/simon/.minikube/ drwxr-xr-x - root 25 oct 17:03 addons .rw-r--r-- 1,3k root 25 oct 17:12 apiserver.crt .rw------- 1,7k root 25 oct 17:12 apiserver.key .rw-r--r-- 1,1k root 25 oct 17:12 ca.crt .rw------- 1,7k root 25 oct 17:12 ca.key .r----x--x 1,0k root 25 oct 17:08 ca.pem drwxr-xr-x - root 25 oct 17:08 cache .r----x--x 1,1k root 25 oct 17:08 cert.pem drwxr-xr-x - root 25 oct 17:08 certs .rw-r--r-- 1,1k root 25 oct 17:12 client.crt .rw------- 1,7k root 25 oct 17:12 client.key drwxr-xr-x - root 25 oct 17:03 config drwxr-xr-x - root 25 oct 17:03 files .r----x--x 1,7k root 25 oct 17:08 key.pem drwxr-xr-x - root 25 oct 17:03 logs drwxr-xr-x - root 25 oct 17:08 machines drwx------ - root 25 oct 17:08 profiles .rw-r--r-- 1,1k root 25 oct 17:12 proxy-client-ca.crt .rw------- 1,7k root 25 oct 17:12 proxy-client-ca.key .rw-r--r-- 1,1k root 25 oct 17:12 proxy-client.crt .rw------- 1,7k root 25 oct 17:12 proxy-client.key
Les permissions étaient en root partout ! C'est pour ça que ça coinçait !
$ sudo chown -R simon:simon /home/simon/.minikube/ $ minikube start Starting local Kubernetes v1.10.0 cluster... Starting VM... Getting VM IP address... Moving files into cluster... Setting up certs... Connecting to cluster... Setting up kubeconfig... Starting cluster components... Kubectl is now configured to use the cluster. Loading cached images from config file.
Yes! Minikube est lancé !
