Task management

Linux

myImage="<insert-my-image-digest>"
baseImage="<insert-base-image-tag>"

function isBuiltOnLatestBaseImage() {
    echo "Pulling $myImage"
    docker pull $myImage

docker run --name test1 -it --entrypoint /bin/sh --privileged <image-name>

In Container:

echo "/cores/core" | tee /proc/sys/kernel/core_pattern
mkdir /cores
ulimit -c unlimited

FROM mcr.microsoft.com/dotnet/sdk:8.0-jammy AS installer

RUN mkdir /pwsh-symlink \
    && ln -s /usr/share/powershell/pwsh /pwsh-symlink/pwsh

FROM mcr.microsoft.com/dotnet/runtime:8.0-jammy-chiseled

COPY --from=installer /usr/share/powershell /usr/share/powershell
COPY --from=installer ["/pwsh-symlink", "/usr/bin"]
