docker-client | A Docker client for Java written in Kotlin and Groovy | Continuous Deployment library

I am trying to pull images behind a proxy.

1. I've setted the docker config file : ~/.docker/config.json :

I'm using the official Docker-registry image to serve as a pull-through cache.

I tried to start it as simple as possible, to minimize sources of error.

I set a proxy on my host machine according to the docker docs in ~/.docker/config.json (https://docs.docker.com/network/proxy/#configure-the-docker-client):

I'm attempting to create a Kubernetes deployment that allows building Docker images and Jenkins on the same host. Here is my YAML configuration for the deployment containing Docker in Docker and Jenkins containers within the jenkins-docker-in-docker deployment:

I’m attempting to execute a Jenkins & Docker CLI container on Kubernetes. Here are my steps:

I create the pod using:

I have an application, that consists of few docker containers: nginx, client, admin, backend and mongo.

In container "backend" is running NestJS application on port 5000. Container has exposed port 5000. But container is not responding to any requests and application inside of container doesn't receive them. I've even tried to expose port 5000 to my local machine so I could make request outside of docker-host but this way container doesn't respond as well. When I'm running this NestJS app locally on my machine everything works perfectly. I have nginx.conf to configure behavior nginx container. It should redirect certain requests to specific containers using proxy. This approach works fine for client and admin containers. Both hosting NextJS application and listening on specific port. I've used the same approach for "backend" container but even though nginx seems to make correct requests, it doesn't receive response or for some reason it makes requests to wrong address inside of docker-host

Dockerfile for my custom images:

The following line in my Dockerfile:

I need to run some docker commands from a java application. So far I've searched and tried both runtime exec and processBuilder approaches but it doesn't work. My last try was with processBuilder trying to execute a bash script containing a docker pull command.

Nothing was printed to the eclipse IDE console, although when i modified the .sh file to do echo 'i am responding' it was printed to the console. To debug the code i modified the .sh script to redirect the stdout and stderr of the docker pull to a file. After opening the resulting file i got: line 11: docker: command not found whereas when i run it in my terminal the docker command works fine. Therefore i am assuming the problem is lies in the java code itself. Where am i going wrong?. Any help would be much appreciated.

Note: I also heard of and tried Spotify docker-client library but I guess my knowledge of Docker is not enough at the moment to set it up. I am using MacOS Big Sur. Here is the java code:

Could anyone point me to description of directory structure that docker registry relies on?

I cannot pull docker image from our company's artifactory server. All my invocations of docker pull art.server.corp/repo/image:label end with error Unexpected EOF. My colleagues report the same issue.

I have asked for help to our Artifactory support, but waiting for their response takes time, and I don't believe in their result.

In the meanwhile I was able to download contents of that image from a browser through a www-interface of the Artifactory.

I've downloaded file manifest.json and bunch of files with names sha256__. Most of them are .tar.gz archives and one is in the JSON format.

How can I import these files into my local docker installation? My goal is to have the same container image as in the registry.

I am new to Docker.

I've tried docker load and docker import. The result is not that expected.

docker load complains about missing json files and does nothing.
