What is K8s External Secrets and how it will make your life easier? Before saying about External Secrets we will say about k8s secrets and how it will work. In k8s secrets we will create key value pairs of the secrets and set this as either pod env variables or mount them as volumes to pods. For more details about k8s secrets you can check my blog http://jinojoseph.blogspot.com/2020/08/k8s-secrets-explained.html So in this case if developers wants to change the ENV variables , then we have to edit the k8s manifest yaml file, then we have to apply the new files to the deployment. This is a tiresome process and also chances of applying to the wrong context is high if you have multiple k8s clusters for dev / stage and Prod deployments. So in-order to make this easy , we can add all the secrets that is needed in the deployment, in the AWS Secret Manager and with the help of External secrets we can fetch and create those secrets in the k8s cluster. So what is K8s external Secret? It is an
VM vs LXC ########## The main difference between the VMs and Containers is that virtual machines require their own kernel instance to run while containers share the same kernel. In other words, containers are virtualization at operating-system-level whereas VMs are virtualization at the hardware level. In virtual Machines each Guest OS will have its own Operating System and kernel. But in the case of LXC Containers the Guest OS will share the same OS of its Host machine. LXC vs Docker ############# LXC is a container technology that gives us the lightweight Linux containers and Docker is single application virtualisation which is based on top of the containerd Run time engine.. Thus even though based on container utilisation they may sound similar but they are completely different when it comes to usage. Unlike the lightweight LXC containers, docker does not tend to behave lightweight VM’s. Single application restriction of the docker is strictly by the design We can easily log o
