Hi Guillaume,

I have also tested this trick and it is reducing the size of the image upto a good extent.

With non multi-stage docker file the size of the image is around 7.57GB

And with multi-stage docker file the size is 3.77GB. Nice !

But when I inspect the image the architecture of the image is changing from amd to arm.

Here is my docker file : 

ARG IMAGE=containers.intersystems.com/intersystems/irishealth:2023.3

FROM --platform=linux/amd64 $IMAGE as builder

# as builder

USER root

RUN mkdir -p /ocie/install

RUN chmod -R 777 /ocie

RUN chown -R irisowner:irisowner /ocie

USER irisowner

COPY --chown=irisowner:irisowner install_app.sh /ocie/tmp/install_app.sh

COPY --chown=irisowner:irisowner AppServer.cls /ocie/install/AppServer.cls

RUN chmod +x /ocie/tmp/install_app.sh

RUN mkdir -p /ocie/scripts

RUN chmod -R 777 /usr/irissys/mgr

# run iris and initial

RUN iris start IRIS \

&& /ocie/tmp/install_app.sh "iris" "localhost" "52773" "/usr/irissys" "/usr/irissys" "DEV"\

&& iris stop IRIS quietly

# # copy data from builder

FROM $IMAGE as final

ADD --chown=${ISC_PACKAGE_MGRUSER}:${ISC_PACKAGE_IRISGROUP} https://github.com/grongierisc/iris-docker-multi-stage-script/releases/l... /irisdev/app/copy-data.py

RUN --mount=type=bind,source=/,target=/builder/root,from=builder \

cp -f /builder/root/usr/irissys/iris.cpf /usr/irissys/iris.cpf && \

python3 /irisdev/app/copy-data.py -c /usr/irissys/iris.cpf -d /builder/root/

 without multi-stage docker file :

docker inspect <imageid>

"Architecture": "amd64",

with multi-stage docker file:

"Architecture": "arm64",

Thanks Enrico,

We were able to drill it and now able to successfully consume the messages from azure blob container.

Hi Yuri,
From where do we get this reference of GatewayContext ? I am getting error at the same line while compiling my java class.

As an overview I am trying to create a reverse Proxy object(Ens.StreamContainer) in my java code and then want to send it (Ens.StreamContainer instead of EnsLib.PEX.Message) to some other business host for processing.
I am not sure whether its doable or not but just wanted to give it a try.

Following this documentation https://docs.intersystems.com/irisforhealth20201/csp/docbook/Doc.View.cl...
