Description Robert P. J. Day 2015-08-13 07:22:08 EDT
When you're using literal strings in a "docker inspect" format string, it seems that if a template resolution fails, leading literal strings can be duplicated. First, an example when it works, both without and with a leading literal string:

sh-4.3# docker inspect -f '{{.Architecture}}' httpd
sh-4.3# docker inspect -f 'My arch is {{.Architecture}}' httpd
My arch is amd64

But look what happens if i misspell as "Archtecture" in both cases:

sh-4.3# docker inspect -f '{{.Archtecture}}' httpd
<no value>
sh-4.3# docker inspect -f 'My arch is {{.Archtecture}}' httpd
My arch is My arch is <no value>
           ^^^^^^^^^^ ???

This is entirely reproducible; just misspell the contents of the template:

sh-4.3# docker inspect -f 'My ports are {{.Config.Ports}}' httpd
My ports are My ports are <no value>

Comment 4 Daniel Walsh 2015-10-23 10:27:49 EDT
Shishir, we need a docker version for this fix.  Did it make it into docker-1.9 or docker-1.10?
Comment 5 smahajan@redhat.com 2015-10-23 10:43:43 EDT
docker 1.9
Comment 6 Lokesh Mandvekar 2016-02-16 14:59:26 EST
Putting this ON_QA as docker 1.9 is already in stable and 1.10.1 is in testing.

no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
