            • As per Adding plots to the basic mplfinance plot(), section Plotting multiple additional data sets
              • Aside from the example below, for two columns from a dataframe, the documentation shows a number of ways to configure an appropriate object for the addplot parameter.
              • apdict = [mpf.make_addplot(data['Upper Band']), mpf.make_addplot(data['Lower Band'])] works as well. Note it's a list, not a tuple.

            How to check whether an app in Docker container ignores Java memory options?
            Asked 2021-Jun-14 at 11:21

            There is a Java 11 (SpringBoot 2.5.1) application with simple workflow:

            1. Upload archives (as multipart files with size 50-100 Mb each)
            2. Unpack them in memory
            3. Send each unpacked file as a message to a queue via JMS

            When I run the app locally java -jar app.jar its memory usage (in VisualVM) looks like a saw: high peaks (~ 400 Mb) over a stable baseline (~ 100 Mb).

            When I run the same app in a Docker container memory consumption grows up to 700 Mb and higher until an OutOfMemoryError. It appears that GC does not work at all. Even when memory options are present (java -Xms400m -Xmx400m -jar app.jar) the container seems to completely ignore them still consuming much more memory.

            So the behavior in the container and in OS are dramatically different. I tried this Docker image in DockerDesktop Windows 10 and in OpenShift 4.6 and got two similar pictures for the memory usage.

            Dockerfile

            ...

            ANSWER

            Answered 2021-Jun-13 at 03:31

            In Java 11, you can find out the flags that have been passed to the JVM and the "ergonomic" ones that have been set by the JVM by adding -XX:+PrintCommandLineFlags to the JVM options.

            That should tell you if the container you are using is overriding the flags you have given.

            Having said that, its is (IMO) unlikely that the container is what is overriding the parameters.

            It is not unusual for a JVM to use more memory that the -Xmx option says. The explanation is that that option only controls the size of the Java heap. A JVM consumes a lot of memory that is not part of the Java heap; e.g. the executable and native libraries, the native heap, metaspace, off-heap memory allocations, stack frames, mapped files, and so on. Depending on your application, this could easily exceed 300MB.

            Secondly, OOMEs are not necessarily caused by running out of heap space. Check what the "reason" string says.

            Finally, this could be a difference in your app's memory utilization in a containerized environment versus when you run it locally.
