Kubernetes on Docker Desktop • Install Docker Desktop • Enable Kubernetes from docker-desktop setting • Switch the Kubernetes context to docker-desktop • Example :

❯ kubectl config get-contexts
CURRENT   NAME                      CLUSTER                   AUTHINFO                  NAMESPACE
          docker-desktop            docker-desktop            docker-desktop
*         kind-kube-nginx-cluster   kind-kube-nginx-cluster   kind-kube-nginx-cluster

❯ kubectl config use-context docker-desktop
Switched to context "docker-desktop".

• Instead of using the command kubectl config use-context docker-desktop we can also go with kubectx to switch between Kubernetes context • To install kubectx on Mac: brew install kubectx #devops #kubernetes #dockerdesktop

We can leverage the AWS Systems Manager service to execute the Ansible scripts on the EC2 hosts, this removes the overhead of maintaining SSH keys and other instance details. How it is done: • Prerequisites: ◦ EC2 instance should have an IAM role attached for SSM ◦ Ansible should be installed on the instance • In the AWS System Manager go to State Manager and create a new association • The association details will include: association name, Document, Ansible playbook, Target selection, schedule, and Rate control • Based on the Association configuration, the playbook will be executed. #automation #awsssm #ansible

Securing Sensitive Data in Kubernetes with Base64 Encoding Today I learned that the base64 command can be used in Kubernetes to encode sensitive data such as passwords and API keys when creating secrets. By encoding the sensitive information in base64 format, it can be safely stored in Kubernetes secrets without exposing it in plaintext. This adds an additional layer of security to the sensitive data used by applications running in Kubernetes clusters. echo -n "some_password" | base64 #devops #kubernetes #encoding
