Python regex to match start and end of sentence

 

#Check if the string starts with "The" and ends with "chennai":

txt = "The rain in chennai"

x = re.search("^The.*chennai$", txt)

Why do we need weekend ??

 

1. To improve on yourself as a person rather than always improving your professional skills.
2. To re-energize yourself, when you go back after weekend, you are more relaxed and productive. A couple of days are really required to forget the rudeness of your office colleagues and managers.
3. To spend time with friends and family, and to plan a weekend trip in a nearby place. It is also important to keep strengthening the bonds with the others around you, and these days you will always remember even when you retire.
4. To spend time alone and learn some new skills. You can meditate and learn about spirituality, or you can enhance your skills in something else, which can help you, if the current technology you are working in, goes outdated. You will come out to be a more confidant and secured person.

Ansible tower / AWX notification Microsoft teams channel

It's not a http header, it's the payload, which you can't alter. 

A WebHook Notification template type won't work for Mattermost/MS Teams/RocketChat or any other Slack compatible communication platform.

Try selecting Mattermost as the notification type and point it to your Teams webhook url; This should do the trick.

k8s pod ??

A pod is the smallest object model that you can create and run. You can add labels to a pod to identify a subset to run operations on. When you are ready to scale your app, you can use the label to tell Kubernetes which Pod you need to scale. 

A pod typically represents a process in your cluster. Pods contain at least one container that runs the job and additionally might have other containers in it called sidecars for monitoring, logging, and so on. Essentially, a pod is a group of containers.

$ kubectl (create|get|apply|delete) -f Resource.yaml

Kubernetes resource model

• Config maps: holds configuration data for pods to consume
• Daemon sets: ensures that each node in the cluster runs this pod
• Deployments: defines a desired state of a deployment object
• Events: provides life cycle events on pods and other deployment objects
• Endpoints: allows an inbound connections to reach the cluster services
• Ingress: a collection of rules that allows inbound connections to reach the cluster services
• Jobs: creates one or more pods and when they complete successfully, the job is marked as completed
• Node: a worker machine in Kubernetes
• Namespaces: multiple virtual clusters backed by the same physical cluster
• Pods: the smallest deployable units of computing that can be created and managed in Kubernetes
• Persistent volumes: provides an API for users and administrators to abstract details about how storage is provided from how it is consumed
• Replica sets: ensures that a specified number of pod replicas are running at any given time
• Secrets: holds sensitive information, such as passwords, OAuth tokens, and SSH keys
• Service accounts: provides an identity for processes that run in a pod
• Services: an abstraction that defines a logical set of pods and a policy by which to access them, sometimes called a microservice
• Stateful sets: the workload API object that manages stateful applications

Command to leave docker swarm

$ docker swarm leave --force

docker update the state of your service by using the command

docker service update

Update docker service with an updated number of replicas.

docker service update --replicas=5 --detach=true [servicename]

verify docker swarm node cluster

docker node ls

To add a worker to this docker swarm

docker swarm join \
    --token **** \
    10.0.120.3:2377

Initialize the docker swarm

docker swarm init --advertise-addr eth0

Check layers of docker image

docker image history [imagename]

Inspect changes to files or directories on a container’s filesystem

docker diff container-id

the docker push command to push your image to the Docker Hub registry:

docker push [dockerhub username]/[image name]

Tag the image with your username.

The Docker Hub naming convention is to tag your image with [dockerhub username]/[image name]. To do this, tag your previously created image python-hello-world to fit that format.

$ docker tag python-hello-world [dockerhub username]/python-hello-world

Log in to the Docker registry account by entering docker login on your terminal

$ docker login
Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one.
Username: 

Run a MongoDB server from the Docker Store

$ docker container run --detach --publish 8081:27017 --name mongo mongo:3.4

inspect the running docker processes:

$ ps -ef

run bash inside container by using the docker container exec command

$ docker container exec -it [container ID] bash 

Inspect the docker container:

$ docker container exec 

This command allows you to enter a running container's namespaces with a new process.

Remove the stopped containers. The following command removes any stopped containers, unused volumes and networks, and dangling images:

$ docker system prune

Stop the docker containers by running this command

$ docker container stop [container id]

Get a list of the running docker containers

$ docker container ls
