Not just for production environments, at every stage in the CI/CD process, you should optimize your docker images.Īlso, with container orchestration tools like Kubernetes, it is best to have small-sized images to reduce the image transfer and deploy time. Therefore, DevOps engineers must optimize the docker images to ensure that the docker image is not getting bloated after application builds or future releases. I have seen cases where the initial application image started with 350MB, and over time it grew to more than 1.5 GB.Īlso, by installing unwanted libraries, we increase the chance of a potential security risk by increasing the attack surface.

This introduces a challenge in Docker image build, as now – the same code requires more time & resources to be built before it can be shipped as a container.
#DOCKER RUN IMAGE IN THE BACKGROUND SOFTWARE#
In typical software development, each service will have multiple versions/releases, and each version requires more dependencies, commands, and configs. Need for Docker Image OptimizationĮven though the Docker build process is easy, many organizations make the mistake of building bloated Docker images without optimizing the container images. First, we add all the build instructions, such as the code dependencies, commands, and base image details, in Dockerfile. The whole concept of “run anywhere” images starts from a simple configuration file called Dockerfile. It enables engineers to collect all the code dependencies and files into a single location which can be run anywhere, quite quickly & easily. We will also look at some of the best tools for Docker Image Optimization.ĭocker as a container engine makes it easy to take a piece of code & run it inside a container.
This blog talks about different optimizations techniques that you can quickly implement to make the smallest and minimal docker image. I want to do some geth utilities command in the shell once the container started and once I exit the shell still expecting the container to be running.If you want to reduce docker image size, you need to use the standard best practices in building a Docker Image. $ docker ps -aĮ27de43da867 ethereum-ubuntu-geth-node2 "entry-point.sh"ġ2 seconds ago Up 11 seconds 8545-8546/tcp, 30303/tcp,īelow are my docker details.

It creates the container and exits the container immediately. Then I run the docker image as container using below command docker run -d -name ethereum-ubuntu-geth-node2 ethereum-ubuntu-geth-node2 When I build the docker image from docker file is it created successfully.
