Password reset too simplistic/systematic issue

Some time when we try to reset the password of our user in linux it will show as simple and systematic as below: BAD PASSWORD: it is too simplistic/systematic no matter how hard password you give it will show the same. Solution: ######### Check if your password is Ok with the below command, jino@ndz~$ echo 'D7y8HK#56r89lj&8*&^%&^%#56rlKJ!789l' | cracklib-check D7y8HK#56r89lj&8*&^%&^%#56rlKJ!789l: it is too simplistic/systematic Now Create a password with the below command : jino@ndz~$ echo $(tr -dc '[:graph:]' 7\xi%!W[y*S}g-H7W~gbEB4cv,9:E:K; You can see that this password will be ok with the cracklib-check. jino@ndz~$ echo '7\xi%!W[y*S}g-H7W~gbEB4cv,9:E:K;' | cracklib-check                 7\xi%!W[y*S}g-H7W~gbEB4cv,9:E:K;: OK Thats all, Thanks.

Running K8s cluster service kubelet with Swap Memory Enabled

For enabling swap memory check the below link : https://jinojoseph.blogspot.com/2019/10/enable-swap-memory-using-swapfile-in.html # sudo vi /etc/systemd/system/kubelet.service.d/10-kubeadm.conf Add the KUBELET_EXTRA_ARGS line as below: ---------------------------------------- Environment="KUBELET_EXTRA_ARGS=--fail-swap-on=false" ExecStart= ExecStart=/usr/bin/kubelet $KUBELET_KUBECONFIG_ARGS $KUBELET_CONFIG_ARGS $KUBELET_KUBEADM_ARGS $KUBELET_EXTRA_ARGS Now kubelet.service changed on disk. Run 'systemctl daemon-reload' to reload units # sudo systemctl daemon-reload # sudo systemctl restart kubelet # sudo systemctl status kubelet That is all cheers :p

Setting /etc/hosts entries during the initial deployment of an Application using k8s yaml file

Some times we have to enter specific hosts file entries to the container running inside the POD of a kubernetes deployment during the initial deployment stage itself. If these entries are not in place, the application env variables mentioned in the yaml file , as hostnames , will not resolve to the IP address and the application will not start properly. So to make sure the /etc/hosts file entries are already there after the spin up of the POD you can add the below entries in your yaml file. cat > api-deployment.yaml apiVersion: apps/v1 kind: Deployment metadata: spec:   template:     metadata:     spec:       volumes:       containers:       - image: registryserver.jinojoseph.com:5000/jinojosephimage:v1.13         lifecycle:           postStart:             exec:               command:...
