Environment variable set twice by docker-compose up command

Question

I have defined a environment variable JAVA_TOOL_OPTIONS in my yaml file. When I start up my containers with the command "docker-compose -f up" I get the following error:

Picked up JAVA_TOOL_OPTIONS: -agentlib:jdwp=transport=dt_socket,address=8010,server=y,suspend=n Listening for transport dt_socket at address: 8010 Picked up JAVA_TOOL_OPTIONS: -agentlib:jdwp=transport=dt_socket,address=8010,server=y,suspend=n ERROR: Cannot load this JVM TI agent twice, check your java command line for duplicate jdwp options. Error occurred during initialization of VM agent library failed to init: jdwp

It looks like the JAVA_TOOL_OPTIONS is set twice. Any help will be very much appreciated

I see your pointing it to a dockerfile, do you have environment variables defined there as well? — Zannith, Mar 06 '19 at 19:11
Yes I do. But not the JAVA_TOOL_OPTIONS environment variable. Below is my Dockerfile — Jugma, Mar 06 '19 at 19:18
So looking at [this post](https://stackoverflow.com/questions/34352006/error-cannot-load-this-jvm-ti-agent-twice-starting-oracle-weblogic-server-12-1). My guess is not the duplicate JAVA_TOOL_OPTIONS but rather an argument specified within it or elsewhere that is coming up as a duplicate when you run the Java command — Zannith, Mar 07 '19 at 16:58
I am sure the JAVA_TOOL_OPTIONS is read twice since the error output clearly says so — Jugma, Mar 07 '19 at 18:02
Yes, that's what I am saying. it is read twice, but setting an environment variable twice wouldn't cause any issue as it simply overrides the previous value. It sounds like there are multiple processes starting up with the same JAVA_TOOL_OPTIONS. For instance a run and a debug connection — Zannith, Mar 07 '19 at 19:12

Try another base java image for your dockerfile. (e.g. 'FROM azul/zulu-openjdk:8u192')

Here's an example of what you're trying to do which you can find here: https://github.com/EricMcEvoyR3/corda-docker-compose (you'll notice he doesn't even set the JAVA_TOOL_OPTIONS variables)

You'll also want to note there's a dockerform task in Corda to generate the task for you: https://docs.corda.net/docs/corda-os/4.4/generating-a-node.html#the-dockerform-task

It looks like you're copying over the correct information in the dokcer-compose file, just take another look at these examples and see if you're able to get this to work.

best of luck on the adventure of building blockchain.
