Absolutely not… LOL. My hope was to identify some high level options for where to start my hunt for this issue because I expect a docker container to run the same in docker desktop on windows 11 as it does in an AWS ECS container using launch type FARGATE. I create the baseline image “FROM amazonc…

How exactly do you deploy each instance? Perhaps there’s a slight difference in configuration or environment that may be the cause

On my local I just use the docker command to run the container. In amazon I use a task definition that points to the image in my repository. Here is an snip from the JSON description of my task: "compatibilities": [ "EC2", "FARGATE" ], "requiresCompatibilities": [ …

[image] jjacobs123: I tag the container for my AWS registry You tag the image, not the container, so your container could work locally and the other container still fail from the same image, because some files are not mounted for example. That si why it is important to see what you are doing …

I am not even sure if ECS still uses Docker or already moved over to contained as runtime. But ECS Services are not vanilla docker. It is neither Docker Compose, nor Docker Swarm, though but none of the differences should result in missing class definitions. It sounds like there is a library colli…

My thoughts exactly, so I spent the weekend cleaning up this legacy web app by moving from a custom ant build to maven. All app dependencies are mapped in the pom file and removed possible collision jars that were installed on the server. Got the app running and tested on my local development envi…

Well, I had some residual jars left over that I missed, and once I removed those all it right with the world!!! Thanks for your thoughts and ideas to all. Still kind of crazy that the container runs differently on a windows docker engine versus a Linux engine, but have to say this wouldn’t be the …

[image] jjacobs123: Looks like I will have open a support case with amazon to see if it is something I am doing wrong or if it’s their docker engine. At this point I’m not confident in migrating legacy apps to ECS. FYI… All of our newer SpringBoot apps run without issue. Are you sure its laga…

This was an old ant build script, but I spent this weekend porting everything over to maven and it made it easier to identify the redundant jars for sure.
