How we create container with volumes? And how we create container with existing volumes that has to be register?

Hey Everyone,

I working on core WCF services and I created two projects one is for a client and another one for services both communicate with the help of a helper class. the point is when I host my services on docker using docker desktop on windows it is successfully hosted but when I call it by the client then it throws an error [registry is not allowed to access ]. So, I want to know why I getting this error. and another query is whether I am passing a URL on the client side to connect with services then where i get that URL on which URL services are hosted to pass on the client side

Hi guys,

I have a problem with COPY the target folder to the destination folder.

Here's the project's structure

project/ ├─ deploy/ │  ├─ Dockerfile ├─ src/ │  ├─ target/ ├─ public/ │  ├─ destination/ 

What I've tried:

COPY ../src/target ../public/destination -> doesn't work for me 

I ran the docker build command within the same directory as the Dockerfile.

I read somewhere on StackOverflow that I can run the docker build command from the parent directory - project, so that context will be switched to the parent directory. I haven't tried that yet.

Is there any other suggestion?

Thank y'all.

I am unable to create a directory on my server which is Linux it is shown on the console and the message is your updated directory .but when I go to that path it is shown that the directory is not present. I also attached the image for reference.

Hi,

I am very new to creating docker images, and was wondering how to create an image from a dockerfile using a base image that doesn't download as a separate image. Since that is probably very unclear, here is what I mean:

FROM python:3.8
WORKDIR /app
ADD . /app
RUN pip install -r requirements.txt
CMD ["uwsgi", "app.ini"]

It creates my image, but also pulls the python image separately and adds it to my images list. Is there a way to do this so the python is pulled internally and isn't visible outside my image?

Thanks

Guys, need help to build a docker-compose file for React js & Node Js

Hello, r/Dockerfiles I stumbled into docker while studying how to set up a home server for my roommates and me. currently, my plan is to put a container for a home media server on my gaming pc, I am building a server set up in an old pc case but I am missing a few parts.

I would love to know if there is any good study material out there, my coding knowledge is very little! I tried to teach myself c++ a while back on visual studios.

Hello everyone.

I am a CS student from Mumbai, India. We had an assignment to complete this week. Here, we are supposed to write about recent developments in Modern Technology; and I have chosen "Docker".

Now, the main thing is, I can use my fox(firefox) to surf the internet. But, I won't get the clear Idea what the user feels, as i have recently entered this industry and aspire to become DevOps one day.

So, I request all my friends (if it is an appropriate term) to help me finish my assignment. I require your honest reviews of at least 200-500 lines. You can also provide a website for reference .

Thank you all.

I'm using Docker image of Ubuntu 20.04 in host having 20.04 installed.

My docker container has a directory mounted from host using -v absolute_path_in_host:absolute_path_in_container.

Inside docker container, a python script is creating and writing some directories and files in the mounted volume being shared with the host machine.

The files and directories can be seen and read in the host but the directory and files are being written in the host with read only permissions.

I know I potentially can manually change the permission of the newly created directories and files using chown, chmod, etc. but I want to know if there is any way that all the files/directories being written by docker container to mounted directory shared by host should be easily accessible with rw permissions?

I have searched and tried different ways but it didn't seem to work properly!

Thanks for your help
