I tried sudo yum update but it just keeps java "1.7.0_75". I need 1.8 for it to work with another application but can't figure out how to upgrade it.
Do I need to manually install it somehow? There's not much information on this on the internet as far as I can see.
Specs: 

java version "1.7.0_75"
OpenJDK Runtime Environment (amzn-2.5.4.0.53.amzn1-x86_64 u75-b13)
OpenJDK 64-Bit Server VM (build 24.75-b04, mixed mode)

When I try update now: 

[ec2-________]$ sudo yum update
Loaded plugins: priorities, update-motd, upgrade-helper
amzn-main/latest                                         | 2.1 kB     00:00
amzn-updates/latest                                      | 2.3 kB     00:00
No packages marked for update

Is there anything else I need to do?
Thanks.

I had an issue with a container, even though it builds perfectly it does not properly start. The cause is a workaround I've added to the Dockerfile (for having a self-configured /etc/hosts routing)

RUN mkdir -p -- /lib-override /etc-override && cp /lib/libnss_files.so.2 /lib-override
ADD hosts.template /etc-override/hosts
RUN perl -pi -e 's:/etc/hosts:/etc-override/hosts:g' /lib-override/libnss_files.so.2
ENV LD_LIBRARY_PATH /lib-override

Obviously there's some error in there, but I wonder how can I get more info on what docker is doing while running. for example, this works:

$ docker run image ls
usr bin ...

But this doesn't:

$ docker run image ls -l
$

There is nothing in the logs and I can't call an interactive shell either. I can use strace to see what's happening but I was hoping theres a better way.

Is there any way I can set docker to be more verbose?

EDIT: Thanks to Andrew D. I now know what's wrong with the code above (I left it so his answer can be understood). Now the issue is still how might I debug something like this or get some insides at why ls -l failed why ls did not.

EDIT: The -D=true might give more output, though not in my case...

I have a running web-application at http://example.com/, and want to "mount" another application, on a separate server on http://example.com/en. Upstream servers and proxy_pass seem to work, but for one issue:

upstream luscious {
 server lixxxx.members.linode.com:9001;
}

server {
  root /var/www/example.com/current/public/;
  server_name example.com;

  location /en {
    proxy_pass http://luscious;
  }
}

When opening example.com/en, my upstream application returns 404 not found /en. This makes sense, as the upstream does not have the path /en.

Is proxy_path the right solution? Should I rewrite "upstream" so it listens to /en instead, as it root path? Or is there a directive that allows me to rewrite the path passed along to upstream?
