'I/O exception (java.io.IOException) caught when processing request to {}->docker://localhost:2376
I am trying to build my project using docker file.
Dockerfile

WORKDIR /app
#copy pom
COPY pom.xml .
#copy source
COPY src ./src
COPY memes-app-ui ./memes-app-ui

RUN --mount=type=cache,target=/root/.m2 mvn clean package -X
# split the built app into multiple layers to improve layer rebuild
RUN mkdir -p target/docker-packaging && cd target/docker-packaging && jar -xf ../memes-app*.jar

when I run mvn clean package in my project I am not facing any issues but with the docker file, I am getting the below error.
