QUESTION
In AWS ECR I have 2 images, and I wish to create an image that is the result of combining the contents of these two images. I have the following Dockerfile to do this:
...ANSWER
Answered 2022-Feb-21 at 09:09You are passing a directory in place of the file argument.
Since you are used the dot, which is the current dir, you can omit the file argument, given the assumption your Dockerfile is called Dockerfile and exists in the context dir. Otherwise, point to it to the actual file.
In any case, use the dot as (last) positional argument to provide the context dir.

I want to dockerize multi-project solution with nested solution file. This is what I tried to do:
Folder structure:
...ANSWER
Answered 2021-Dec-07 at 11:37You can't move up a directory like you do with the source file in COPY ["../Project1/Project1.csproj", "../Project1/"]
.
That takes you outside the build context and that's not allowed for security reasons.
You need to move your Dockerfile up a directory and adjust the paths in the Dockerfile. That way all the files you want to copy are in the same directory as the Dockerfile or in directories below that.
Here's my guess at how your Dockerfile should look based on your directory structure
QUESTION
I am building a docker image and need to include some contents from particular url. So I make a curl request and get the contents as a zip. I am able to extract the zip into a folder as well. However in the very next line if I try to copy the folder I get error that such file or folder does not exist. Can someone help me? Below is the docker file. If I do a ls -a after the unzip I can see 2 items drop and amui which is correct. But very next line if I try to copy it fails.
...ANSWER
Answered 2021-Sep-29 at 16:16Make sure the file or folder is present in the location you expect it to be. The WORKDIR /app
from the FROM abc.io/aspnet-runtime:3.1.6 AS base
sets the working directory for all contexts until there's another WORKDIR
encountered, thus even for the ones that "inherit" from the previous one (FROM previous as new
) or for the RUN
context. Once that is out of the way, for the remaining part it's about contexts created by FROM
and its order.
QUESTION
I have a multi layered project and a third party DLL file and I want to dockerize them. I added a dockerfile into my webApi project and tried to build it but this error occurred:
3>Step 7/22 : COPY ["D:/MultiLayeredProject/output/MultiLayeredProject/PluginProject.dll", "MultiLayeredProject/"] 3>COPY failed: stat /var/lib/docker/tmp/docker-builder959745697/D:/MultiLayeredProject/output/MultiLayeredProject/PluginProject.dll: no such file or directory 3>C:\Users~~\source\repos\MultiLayeredProject\MultiLayeredProject\Dockerfile : error CTC1014: Docker command failed with exit code 1. 3>C:\Users~~\source\repos\MultiLayeredProject\MultiLayeredProject\Dockerfile : error CTC1014: COPY failed: stat /var/lib/docker/tmp/docker-builder959745697/D:/MultiLayeredProject/output/MultiLayeredProject/PluginProject.dll: no such file or directory
How can I add an external DLL to the dockerfile? My dockerfile is like below:
...ANSWER
Answered 2021-Sep-12 at 09:04As I understand, your third-part dll is a part of project folder. So, instead of using absolute path to file, try to use relative path, like:
COPY ["output/MultiLayeredProject/PluginProject.dll", "MultiLayeredProject/"]
When you call docker build
, docker cli sends your project structure (context) to docker daemon (inside Linux OS) and there is no D:/...
path.

Answered 2021-Apr-24 at 07:41Docker is reading my .gitignore content and ignoring files and folder in it. I have ignored jar files in gitignore so its ignoring that while copying. Need to make sure .gitignore file is not having those files ignored which you are copying in docker file.

QUESTION
I have 1 folder that contains several dockerfiles, and i want to specify which is the one i want to build. In this case i'm suposed to use
...ANSWER
Answered 2021-Jan-12 at 08:10This is an expected behaviour.
Quoting the statement from official doc.
$ docker build - < Dockerfile
This will read a Dockerfile from STDIN without context. Due to the lack of a context, no contents of any local directory will be sent to the Docker daemon. Since there is no context, a Dockerfile ADD only works if it refers to a remote URL.
With -
, docker build reads from STDIN without context causing problem while adding or copying the files during the build process. In case of docker build .
command, the context is used and hence the copying/adding files works.
Also if you want to specify a specific dockerfile during the build, then use -f option.
QUESTION
I am trying to setup an Azure Container Registry (ACR) to automatically build Docker images when I commit changes to my Git repository.
The problem I'm having is that my Dockerfile is in a folder within the respository. This works, in that Azure retrieves the source code and starts to build the Docker image. However, the Dockerfile refers to files relative to the location of the Dockerfile (i.e. inside the folder). When the ACR Task tries to build the image, it complains that the files can't be found. I suspect it's because it's looking for them in the root of the repository, not in the same folder as the Dockerfile.
Here's how I created the Task:
...ANSWER
Answered 2020-Nov-26 at 02:20For this issue, you can first take a look at the context of the docker build
. As it shows, I recommend you make some changes to the Dockerfile. The best way is to put the Dockerfile in the root folder of the repository, and then copy files in the Dockerfile with a relative path according to the root folder.
Of course, you can keep the current directory structure, then you need to change the COPY
path relate to your Git repository root folder.
