@edurekaIN 5 лет назад

Hey Nitin, docs.docker.com/v17.09/engine/userguide/eng-image/dockerfile_best-practices/#env. This should help you. Cheers!

@RavindraRaivlogs 4 года назад

@widadcadi2950 3 года назад

Good explanation

@raagithagummadi1038 5 лет назад

I started learning devops recently from your videos. Guys I have a doubt here please solve. After testing Jenkins package everything including code and dependencies into a war/jar file. Even dockerfile contains application's source code and dependencies. Now if we are using the docker container to deploy onto production server. Now where do we use the war file that is generated from JEnkins? someone please clarify.

@edurekaIN 5 лет назад

Hey Raagitha! The WAR file that is created by the Continuous Integration server is put in the docker container..to package it as a container. Then, the container is used in the testing or the production server.

@bhavanichennam5477 5 лет назад

Hi sir u have used cmd in the Apache server to start and entry point in nginx server the 2 builts were success what actually to be used

@navyasriveluri 5 лет назад

is the Nginx.conf file created during this process? if not what should I do in order to get the Nginx.conf file?

@edurekaIN 5 лет назад

Hi Navyasri, By default, the configuration file is named nginx.conf and placed in the directory /usr/local/nginx/conf. Sometimes at other locations like /etc/nginx, or /usr/local/etc/nginx. Hope this helps. Cheers!

@ashweenikodag1257 5 лет назад

@nitin9281 5 лет назад

In both the dockerfile -d and -g flag what does it means ?

@edurekaIN 5 лет назад

Hey Nitin, "I need to know the context -d is usually used with run ... its for detaching" Hope this helps!

@sweetwoodbunnies 5 лет назад

@mohittayal9731 4 года назад

What is base image? I mean how can I got to know that my application need this base Image? How I decide this ?

@edurekaIN 3 года назад

Dockerfile usually starts from a base image. As defined in the Docker documentation, a base image or parent image is where your image is based. It's your starting point. It could be an Ubuntu OS, Redhat, MySQL, Redis, etc. Every application will need a base image. You can create it from scratch as well but that is something for more advanced users.

@dhanashreekulkarni7197 6 лет назад

Hello, This was very informative tutorial. Although I havent fully understood USER command. I have a Dockerfile in which I have created a user 'ubuntu'. I have built docker image using this Dockerfile. The problem comes when I use this image in my OpenShift environment and run the container using this image, I get error: sudo: unknown uid 1000110000: who are you? I am using this Dockerfile (github.com/dhanugithub/omdockerimage). Can you please help me understand what I am doing wrong here? Being a fresher in Docker, I don't have deep knowledge of it as of now. Thank you.

@edurekaIN 6 лет назад

Hey Dhanashree, This usually occurs when the current UID that you're using is not present in etc/passwd. Check the etc/passwd file for this uid. Follow these steps to check step 1- strace -f -F -o whoami whoami you'll get a file called whoami, parse it grep etc whoami 5029 open(/etc/passwd", O_RDONLY|O_CLOEXEC) = 3 There could be another cause, by any chance do you have apparmour installed? Maybe its blocking something, try uninstalling it. If this doesn't solve the problem, put this question up on the following link: www.edureka.co/community/ Hope this helps!

@dhanashreekulkarni7197 6 лет назад

Hello, I managed to resolve the issue of uid. Now I have uid, gid of USER in dockerfile inside /etc/passwd of my container. I still have other issues but not regarding USER for now. Thank you for the guidance. I will write again if I have another doubt.
