Docker training provides an open-source project that automates the deployment of Linux applications inside the software containers. Docker also uses the resource isolation features of the Linux kernel such as c groups and kernel namespaces and a union-capable file system.

INTRODUCTION ABOUT DOCKER TRINING Docker Training is an open-source project that automates the deployment of Linux applications inside the software containers. Docker also uses the resource isolation features of the Linux kernel such as c groups and kernel namespaces and a union- capable file system such as Overlay FS and others to allow independent “containers” to run within a single Linux instance, avoiding the overhead of starting and maintaining virtual machines. Docker training module is arranged on interactive virtual platform and with flexi timing advantage for offering all its participants excellent advantage of using their spare time to pursue the training for better career exposure
PREREQUISITES OF DOCKER TRAINING: People who have knowledge in these skills can enlist in the Docker Trainin Awareness in Unix, AWS and, Linux administrator.
OVERVIEW OF DOCKER TRAINING: Docker is the standardized technology in the DevOps. This is the open source container technology, the container will allow the developers to put the applications everywhere in the stack and runs depended applications, that will be packed up in a box which is in the separate environment To run the business for the big companies go with the billions containers through the data centers regularly. So, it helps them to keep continuous integration and delivery. Docker makes the work easy; this technology is super fast and great development for the further software development.
COMPONENTS OF THE DOCKER: (DOCKER TRAINING) Docker Daemon runs the whole machine that is the containers inside the daemon. Whereas the docker client which the CLI will be using to interact with the daemon. If you are using the Linux machine you can run the docker client outside of the machine. If you are a windows user, then there will be an extra layer that is boot2docker For that first you need to install the virtual box and then boot2docker that will give you a separate environment. These contain layers. The base operating system has versions like version-1 and version-2. We work on the version-1 according to the application and then go for the version-2 development we add another layer.
COMPARE DOCKER WITH THE VIRTUAL MACHINES: (WITH THE DOCKER TRAINING) Docker is fast than the virtual machine; Virtual Machine takes the 3 minutes to boot up with the docker it will complete within seconds. Docker containers are portable; through the docker hub you can easily port them. Virtual Machine’s are not portable; you need to have some network for that and it takes 4 to 5 hours time to transfer. Like the GitHub we have for code, Docker hub that is used to store the docker images, it is the open source and have to pay for the repositories,
DIFFERENCES BETWEEN UNIVERSAL FORWARDER AND THE HEAVY FORWARDER: About the footprints in the forwarders, it will be light in weight for the Universal forwarder, and heavy in weight for the heavy forwarder. The universal forwarder has separate packages and they cannot filter the data. The Heavy forwarder can filter, in the heavy forwarder it has the packages same as the indexer has. The heavy forwarder is used for the universal forwarder and for the indexer. You will come across the term Search head that is used for the index search.
