I’ve found quite a few blogs on how to run your jenkins in docker but none really explain the advantages of doing it. These are the only reasons I found (https://twasink.net/2016/08/01/setting-up-a-jenkins-server-with-docker/) : 1) I want most of the configuration for the server to be under version control. 2) I want the ability to run the […]
I want to upload container-images containing my java applications onto docker using which I will deploy pods. Is there Java API which provides this functionality? I require these two functionalities: Uploading of java images onto docker from outside. Pushing these images onto docker registry. Thanks in advance.
I created docker container with mysql using -v option: -v /storage/mysql1/mysql-datadir:/var/lib/mysql When i removed container i lost database saved in /var/lib/mysql . How can i create mysql container with -v option (to see everything from the host) and not lost the data?
My current approach is to have logging to stdout for each container and then get docker to send that to syslog, or to syslog to a remote syslog if the container cannot do stdout, and setup logstash to be that syslog sink. Does AWS offer any facility for logging that I should be considering instead?
I’m currently trying to automate our dev process using CodePipeline. My docker application fetches from the Source(Github) -> Builds(AWS CodeBuild) -> Deploy. In the final deployment process, I’m having trouble revising my task definition and restarting my cluster tasks. I understand that I need a CloudFormation template to perform these actions, but there isn’t much […]

I’m using AWS ECS to deploy my group of docker containers and in bridge network mode all works perfectly but with a slow performance… I’ve read that this problem resolves with a host network mode but if i use this, it causes an error on containers deploy (some of them), “CannotCreateContainerError: Container already exists”. Looking […]
I’m trying to dockerize a wpf application. Just a simple app for that time. for now i got this dockerfile : FROM microsoft/nanoserver WORKDIR C run “$PATH” #ENTRYPOINT [“C:\Users\TestDev\Documents\Visual Studio 2017\Projects\TestExe\TestExe\bin\Release\TestExe.exe”] RUN [“C:\Users\TestDev\Documents\Visual Studio 2017\Projects\TestExe\TestExe\bin\Release\TestExe.exe”] Si i tried with entrypoint, run and cmd. But got this error : The filename, directory name, or volume label […]
New to docker… Need some help to clarify basic container concept… AFAIK, each container would include app. code, library, runtime, cfg files, etc. If I would run N numbers of containers for N numbers of app. and each of the app. happens to use a set of same lib. would it mean my host systems […]
I read, that Docker uses libcontainers and rkt uses systemd-spawn to access Linux kernel. Although some web-sites are saying Docker can use systemd-spawn as well, so I am confused. What is the difference between it and how to know, what is the relevant way they do so?
