How to build a Docker Image in Matlab with Additional Packages

I have a function that works. I am able to dockerize it without adding additional packages, but when i add additional packages i get error messages.

mpsResults = compiler.build.productionServerArchive ('DockerFunction_ToTest_Reading_Inserting_Into_AWS.m')
compiler.package.microserviceDockerImage(mpsResults,'ImageName','dockertotestconnectiontoaws','AdditionalPackages',"postgresql-42.7.0.jar")

I have 2 questions - 1) What path does Matlab expect my JAR file to be in, it is in the current (pwd) director 2) How can i mention specific path in the above command ?

I tried the following variations of adding the Additional Package none worked -

compiler.package.microserviceDockerImage(mpsResults,'ImageName','dockertotestconnectiontoaws','AdditionalPackages','postgresql-42.7.0.jar')
compiler.package.microserviceDockerImage(mpsResults,'ImageName','dockertotestconnectiontoaws','AdditionalPackages','\\gcnms101.ds.givaudan.com\HomeDirL$\sivar\Documents\Rahul\ATOM 3\Mfiles New\ATOM 3 APIs\postgresql-42.7.1.jar')
compiler.package.microserviceDockerImage(mpsResults,'ImageName','dockertotestconnectiontoaws','AdditionalPackages','C:\Program Files\MATLAB\R2023a\java\jar\postgresql-42.7.0.jar')
compiler.package.microserviceDockerImage(mpsResults,'ImageName','dockertotestconnectiontoaws','AdditionalPackages','C:/Program Files/MATLAB/R2023a/java/jar/postgresql-42.7.0.jar')
compiler.package.microserviceDockerImage(mpsResults,'ImageName','dockertotestconnectiontoaws','AdditionalPackages',"./postgresql-42.7.0.jar")
compiler.package.microserviceDockerImage(mpsResults,'ImageName','dockertotestconnectiontoaws','AdditionalPackages',"postgresql-42.7.0.jar")
compiler.package.microserviceDockerImage(mpsResults,'ImageName','dockertotestconnectiontoaws','AdditionalPackages',"C:/Program Files/MATLAB/R2023a/java/jar/postgresql-42.7.0.jar")
compiler.package.microserviceDockerImage(mpsResults,'ImageName','dockertotestconnectiontoaws','AdditionalPackages',"C:/Rahul/postgresql-42.7.0.jar")

You can add additional files with AdditionalFiles of compiler.build.ProductionServerArchiveOptions.

functionFile = 'DockerFunction_ToTest_Reading_Inserting_Into_AWS.m';
opts = compiler.build.ProductionServerArchiveOptions(functionFile, 'AdditionalFiles', 'postgresql-42.7.2.jar');
buildResults = compiler.build.productionServerArchive(opts);
compiler.package.microserviceDockerImage(buildResults);

Hi Kojiro Saito Thank you very much for your response. I have a follow up question - how do i specify the path of the 'postgresql-42.7.2.jar' file. I am assuming i can do it 'D:\Documents\MATLAB\work\postgresql-42.7.2.jar' etc. I am asking because that did not work when i tried to add the path this way in the compiler.package.microserviceDockerImage command.

[Kojiro Saito]

The abobe would be the following.

functionFile = 'DockerFunction_ToTest_Reading_Inserting_Into_AWS.m';
opts = compiler.build.ProductionServerArchiveOptions(functionFile, 'AdditionalFiles', 'D:\Documents\MATLAB\work\postgresql-42.7.2.jar');buildResults = compiler.build.productionServerArchive(opts);
compiler.package.microserviceDockerImage(buildResults);

compiler.package.microserviceDockerImage does not have an option of AdditionalFiles, so you'll need to specify in compiler.build.ProductionServerArchiveOptions.

Hi Kojiro Saito - Thank you so much. This worked. Very much appreciate your time.

Hi @Kojiro Saito I have one more question that my IT team wants to know. The dockerized image created by matlab can they run in a unix environment ? Or only in linux environment ? I am checking the help documents it seems Matlab create dockerized containers will only run on linux, windows and mac environments and not unix, is this correct ? Is there some workaround to make the containers run in a unix environment ?

Thanks for all your help and your time.

MATLAB Docker container images are Ubuntu based and you can run them from Linux, Mac and Windows environment. It may run but we don't test on Unix.
