Ask questionsnotes for "Shell form ENTRYPOINT example" need to be cleaned up

File: engine/reference/

These points relate to Several points:

  1. The following Dockerfile does not build:
FROM ubuntu
CMD --ignored-param1
# docker build -t top .
Sending build context to Docker daemon  70.14kB
Error response from daemon: Dockerfile parse error line 6: Unknown flag: ignored-param1
  1. command output conflicts with argument(s?) to docker run in the example given:
$ docker run -it --name test top --ignored-param2

Mem: 1704184K used, 352484K free, 0K shrd, 0K buff, 140621524238337K cached
CPU:   9% usr   2% sys   0% nic  88% idle   0% io   0% irq   0% sirq
Load average: 0.01 0.02 0.05 2/101 7
    1     0 root     S     3168   0%   0% /bin/sh -c top -b cmd cmd2
    7     1 root     R     3164   0%   0% top -b

Command gives --ignored-param2, while output uses cmd cmd2. This is besides the fact that the container's output from top does not reveal the command line arguments for both sh and top; you need to use docker top test for that.

  1. The table at needs to be updated. Specifically the ENTRYPOINT exec_entry p1_entry, with CMD exec_cmd p1_cmd entry. I get /bin/sh -c exec_entry p1_entry sh -c exec_cmd p1_cmd

Answer questions jf

My testing for the table shows otherwise. Have you tested it?
