Maintain and Manipulate Docker Containers
Knowing how to create a dockerfile and build a docker image using that dockerfile, we can move ahead and dive deep into more advanced ways to manipulate docker containers. When we talk about manipulating docker containers, we include running, listing, restarting, cleaning up the dangling containers, running containers in interactive and detached modes, creating containers using executable images, executing commands inside docker containers using exec command and starting a bash inside a container, accessing logs from a docker container and killing or stopping a docker container.Without any further ado, let’s dive deep into manipulating docker containers.Running docker containersAfter you have ...
Read MoreBuilding a full-fledged data science Docker Container
No doubt that the buzzing words in the technological world these days are machine learning and artificial intelligence. More rapidly than ever, organizations are now trying to adopt machine learning techniques to analyse and improve their businesses and to provide more customer satisfaction. While on the other hand, the revolutionary concept of containerization has made the lives of millions of developers a lot easier and has helped them in adopting better techniques to maintain, reuse and keep track of their projects a seamless experience.In this article, we will talk about how to build a full fledged data science container. We ...
Read MoreHow to run a command inside Docker Container?
After you build a docker image and you have created a running instance of it or in other words, you have created a docker container, you might want to execute some commands inside the docker container to either install a package or print something or browse through the directories inside the container. Docker provides you with several ways to do exactly the same. You can easily access the container environment, execute commands inside the environment and access or create files and directories there too. In this article, we will discuss some ways to run or execute commands inside the docker ...
Read MoreDocker Image tags and how to use them
Docker Image tags are simple labels or aliases given to a docker image before or after building an image to describe that particular image. It can be the version of the project or the container, features of the image, technologies used in the image or pretty much anything you want. It plays a key role in the overall software development life cycle because it helps you keep track of the different parts of your project as well as help you in version management of the product.While pulling an image, you can specify the tag of the image you want or ...
Read MoreSearching and pulling Docker Images from Dockerhub
The official Docker registry contains a lot of pre-built images and publicly available customized images that are very useful and can be easily pulled by the users in their local machine and used as base images for their projects. In fact, you can also build your own customized docker image using one of those publicly available docker images and push it back either in a public or private mode.In this article, we will discuss how to search for a docker image using the search command through the command line interface. We will also see how to filter the search results ...
Read MorePublishing a Docker Image on Dockerhub
Dockerhub or the official docker registry consists of numerous pre-built Docker Images as well as customized images by other users that you can pull to your system if they have been made public. In order to pull or push images to the docker registry, you need to first have an account in Dockerhub.To create an account and a repository in dockerhub, you can follow these steps −Visit the docker hub (Link − https://hub.docker.com/).Create an account or if you already have one, sign in with your account details.After signing in, click on create repository on the welcome page.Fill in the details ...
Read MoreImportant instructions used in dockerfile
We all know the importance of dockerfile in creating an efficient and flexible Docker Image. A dockerfile contains a set of instructions that are executed step by step when you use the docker build command to build the docker image. It contains certain instructions and commands that decides the structure of your image, the amount of time taken to build the image, contains instructions related to docker build context, contains information related to the packages and libraries to be installed in the container and many more. Hence, it becomes very important to create an efficient, reusable, clean dockerfile as it ...
Read MoreWorking with Docker Volumes
To define Docker Volumes, they are file systems that can be mounted on Docker containers. They help in preserving the data and are independent of the container life cycle. One of the major advantages of Docker Volumes is that it allows the developers to backup their data and also allows easy sharing of file systems among Docker containers. We can easily mount a volume when we launch a Docker container. It is also possible to mount the same volume to different containers and this allows easy sharing of data between them and this can be easily achieved with the use ...
Read MoreHow to backup and restore a Docker Container?
Docker allows us to automate the process of building and deploying an application. It also allows us to create a packaged environment to run the application which makes it easily portable and lightweight while also allowing us to keep track of the versions. All of these are possible through Docker Containers. It helps in making the applications platform independent.Let’s say we have a docker container running in our machine and we want to take a snapshot or keep a backup of that container so that in case of any emergency, if we want to roll back changes or execute a ...
Read MoreCopy Files from Docker Container to Local Machine
If you are working on a project that requires frequent copying of files and folders either from container to your local machine or from the local machine to the container, docker provides an easy and simple way to do that. If you have already built a docker image which is of large size and contains a large number of files and in the midst of the project you want to copy files to and from the container, it’s highly inefficient to put the files in the docker build context and build images repeatedly. Instead, docker allows easy copying of files ...
