Create modified Docker image
Software prerequisites
Installed Docker or Docker Desktop
Ability to run shell scripts
Let's say we want to use the Smartstore Community Edition Docker Image, but have a self-developed or third party plugin that we also want to use. How do we get the new plugin into the Docker image?
The example is run under Windows, but it will be similar under Linux.
Download the Community Edition
We download the release of the Community Edition from GitHub. It is important that the versions of the release and the plugin are the identical.
For the Docker image we need the Linux release of Smartstore.
We create a subfolder, name is not relevant, I simply named the folder build_my_docker_image. Here we create another folder called smartstore-linux-x64 and unpack the contents of the file into this folder.
We place our own or third party plugin in the \Modules folder in the \smartstore-linux-x64 folder. Not as a zip file, but unpacked.
Now we need the Dockerfile and the script file with the instructions for creating the Docker image.
We create an empty text file in the build_my_docker_image folder with the file name Dockerfile (without an extension, just Dockerfile), copy the following content into it and save the file.
# -----------------------------------------------------------
# Creates a Docker image from an existing build artifact
# -----------------------------------------------------------
ARG ASPNET_TAG=7.0
FROM mcr.microsoft.com/dotnet/aspnet:${ASPNET_TAG}
EXPOSE 80
EXPOSE 443
ENV ASPNETCORE_URLS "http://+:80;https://+:443"
# Copy
ARG SOURCE=/smartstore-linux-x64
WORKDIR /app
COPY ${SOURCE} ./
# Install wkhtmltopdf
RUN apt update &&\
apt -y install wget &&\
wget https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6-1/wkhtmltox_0.12.6-1.buster_amd64.deb &&\
apt -y install ./wkhtmltox_0.12.6-1.buster_amd64.deb &&\
rm ./wkhtmltox_0.12.6-1.buster_amd64.deb
ENTRYPOINT ["./Smartstore.Web", "--urls", "http://0.0.0.0:80"]
We repeat the whole thing for the file dockerize.linux.nobuild.sh. So we create a new text file, copy the following content into it and save the file.
docker build -t smartstore-linux-image -f Dockerfile .
echo 'Press enter to exit...'; read dummy;With the -t switch, the image is "tagged", i.e. given a name. These can be changed by smartstore-linux-image as desired.
The result should look like this:
By running the file dockerize.linux.nobuild.sh we can create the new image.
