> Now on each time AM Container crashes during launch, both the console and the webpage
UI only report a ShellExitCodeExecption. This is not only unhelpful, but sometimes confusing.
With the help of log aggregator, container logs are actually aggregated, and can be very helpful
for debugging. One possible way to improve the whole process is to send a "pointer" to the
aggregated logs to the programmer when reporting exception information.
