Read moreQ1. Explain What is Docker Container with image? Docker container with image is an running image, which have the basis things like ROOT FS, PID NS, USER NS, and NET NS. Q2. What is the differenece between docker stop and docker kill? the difference i observed was during the stop the exit value is zero (0) and during the kill i was getting non zero value (137) ubuntu@ip-172-31-28-155:~$ sudo docker stop abhinabhinubuntu@ip-172-31-28-155:~$ sudo docker ps -a | grep abhin28525b0ff5df httpd

Read moreA docker container is an environment or a setup which is used to run an application. The environment is created with the help of images. Later on we can share the environment with the respective developer or client.

As soon as you know the tiny stuff and understand the place of your terrain, you can expect to begin investing for dollars. This post can place you on the

Read moreWhat is Array’s Manual indexing? when we create our own indexing in an array is known manual indexing. in which we change default indexing starting from zero ‘0’ index. we can keep values in our own indexing using “=>“this operator. for example. Syntax “index => values“, separated by commas, define index and values. Index may be of type string or integer. When index is omitted, an integer index is automatically generated, starting at 0. If index is an integer, next

SDLC or the merchandise Improvement Life Cycle is an interaction that produces programming with the best and most reduced expense within the briefest time conceivable. SDLC gives an awfully much-organized progression of stages that assist an association with rapidly creating great programming which is all around tried and ready for creation use. It comprises of an itemized plan portraying the way to create, maintain with, supplant and alter or improve explicit programming. Why SDLC

What is Software Development Lifecycle (SDLC)? Software Development Life Cycle (SDLC) is a process employed by the software industry. It helps to style, develop and test top quality software. it’s a technique which has clearly defined processes for creating low-cost and high-quality software. It provides a well-structured flow of phases which help a corporation to supply high-quality software quickly which is well-tested and prepared for production use. Why do we need SDLC? A system development life cycle helps to minimize the complexity of developing a system from scratch. It’s important to possess an SDLC in situ because it helps to rework the thought of
Read moreWhat is Docker volume and how to work with it? Docker volumes are file systems mounted on Docker containers to preserve data generated by the running container. The volumes are stored on the host, independent of the container life cycle. This allows users to back up data and share file systems between containers easily. To create a Docker Volume use the command: Mounting a Data Volume: What is Kubernetes pod? Pod is a Logical definition of Running applications in Kubernetes.
Read moreWhat is Docker volume and how to work with it? They are file systems that can be mounted on Docker containers To store data in a volume rather than storing it in a container’s writable layer as it does not increase the size of the container Docker volume can be shared with more than one container 2.What is Kubernetes pod? A collection of one or more containers, and is the smallest unit of a Kubernetes application. A pod is the
Read moreWhat are Docker Volumes? Docker volumes are file systems mounted on Docker containers to preserve data generated by the running container. The volumes are stored on the host, independent of the container life cycle. This allows users to back up data and share file systems between containers easily. There are different ways to mount a Docker volume while launching a container. Users can decide between the -v and the –mount flags, which are added to the docker run command. Mounting
Read moreA pod is the smallest execution unit in Kubernetes. A pod encapsulates one or more applications. Pods are ephemeral by nature, if a pod (or the node it executes on) fails, Kubernetes can automatically create a new replica of that pod to continue operations. Pods include one or more containers (such as Docker containers). Pods also provide environmental dependencies, including persistent storage volumes (storage that is permanent and available to all pods in the cluster) and configuration data needed to

Read moreWhat’s New (Major Themes)Removal of several beta Kubernetes APIsA number of APIs are no longer serving specific Beta versions in favour of the GA version of those APIs. All existing objects can be interacted with via general availability APIs. This removal includes beta versions of ValidatingWebhookConfiguration, MutatingWebhookConfiguration, CustomResourceDefinition, APIService, TokenReview, SubjectAccessReview, CertificateSigningRequest, Lease, Ingress, and IngressClass APIs. For the full list check out Deprecated API Migration Guide and the blog post Kubernetes API and Feature Removals In 1.22: Here’s What
