custom truststore with stroom-proxy docker image

[duncanlester]

Hi,
I am having some issues using the gchq/stroom-proxy:latest build.
I can curl my stroom with the custom truststore but cannot work out where i need to place the truststore or how to configure the stroom.properties file:

javaOpts="-Djavax.net.ssl.trustStore=/etc/ca-certificates"

error i get from the proxy log:

I hope this is the right place for this.

Cheers
