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/… /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",

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.cls?KEY=BJAVNAT_gateway#BJAVNAT_gateway_irisobject_create
