Julia workers in containers. `stdout` issue

General Usage
1

Hi, I am experiencing a strange issue with Julia workers running in docker container instances in Azure . I am able to run distributed computations on workers, so everything seems fine, except that workers don’t print anything. E.g.

julia> workers() 
2-element Vector{Int64}: 
2 
3

julia> @everywhere println(myid()) 
1

Not sure how to debug it. Please let me know if you have an idea

Perhaps the container stdout needs to be redirected in some way…

Thanks for your response. Yes, it seems the problem is with standard redirect_worker_output:

function redirect_worker_output(ident, stream)
    t = @async while !eof(stream)
        line = readline(stream)
        if startswith(line, "      From worker ")
            # stdout's of "additional" workers started from an initial worker on a host are not available
            # on the master directly - they are routed via the initial worker's stdout.
            println(line)
        else
            println("      From worker $(ident):\t$line")
        end
    end
    errormonitor(t)
end

eof(stream) in my case is true so the output is not printed. So the problem is not with julia but with container interrupting the log stream for some reason.
