Existe um curso sobre Kubernetes na IBM Cloud, o link é o seguinte https://courses.cognitiveclass.ai/
Os exemplos do curso estão no GitHub https://github.com/IBM/container-service-getting-started-wt
Pré-requisitos
Instalando os pré-requisitos
No MacOS
brew install kubectl brew cask install ibm-cloud-cli brew install cfssl brew install docker
Login na IBM Cloud
ibmcloud login
Para FederatedID (Ex. Funcionário IBM)
ibmcloud login -sso
Install the IBM Cloud plug-ins
Install the IBM Cloud Kubernetes Service plug-in to create Kubernetes clusters and manage worker nodes by installing the IBM Cloud Kubernetes Service plug-in:
ibmcloud plugin install container-service -r Bluemix ibmcloud plugin install container-registry -r Bluemix
Listando plug-ins instalados...
ibmcloud plugin list
- Nome do Plug-in Versão
- container-service/kubernetes-service 0.1.593
Provisionando um Cluster na IBM Cloud
Vá no endereço https://console.bluemix.net/catalog/ e localize a entrada IBM Cloud Kubernetes Service.
Deploy da sua Primeira aplicação no IBM Cloud
Push da imagem para o IBM Cloud Container Registry
Clonando os exemplos do Github
mkdir Curso git clone https://github.com/IBM/container-service-getting-started-wt.git
Login na IBM Cloud
bx login --sso
Login na IBM Cloud Container Registry.
bx cr login
Criando uma namespace
bx cr namespace-add <my_namespace>
Criando uma docker image
docker build --tag registry.ng.bluemix.net/<my_namespace>/hello-world:1 .
Verificando a imagem
docker images
Fazendo o push da image
docker push registry.ng.bluemix.net/<my_namespace>/hello-world:1
Verifique que o cluster está pronto pra uso
bx cs clusters # verificar se o estado está normal bx cs workers <yourclustername> # Verifica se os workers estão no estado "Normal" com o status "Ready"
Anotar o ip público do worker.
Deploy da aplicação
Execute o comando e defina as variáveis de ambiente
bx cs cluster-config <yourclustername>
Exemplo no Mac
export KUBECONFIG=/Users/<user_name>/.bluemix/plugins/container-service/clusters/pr_firm_cluster/kube-config-prod-par02-pr_firm_cluster.yml
Iniciando a aplicação
kubectl run hello-world --image=registry.ng.bluemix.net/<my_namespace>/hello-world:1
Verifique o status pelo comando
kubectl get pods
Quando o status estiver como Running, execute
kubectl expose deployment/hello-world --type="NodePort" --port=8080
Para achar a porta
kubectl describe service <name-of-deployment>
Para remover o Deployment
kubectl delete deployment hello-world.
Para remover o Service
kubectl delete service hello-world.
