Ask questionsnotes for "Shell form ENTRYPOINT example" need to be cleaned up
These points relate to https://docs.docker.com/engine/reference/builder/#shell-form-entrypoint-example. Several points:
FROM ubuntu ENTRYPOINT top -b 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 #
docker runin 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 PID PPID USER STAT VSZ %VSZ %CPU COMMAND 1 0 root S 3168 0% 0% /bin/sh -c top -b cmd cmd2 7 1 root R 3164 0% 0% top -b
--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
top; you need to use
docker top test for that.
ENTRYPOINT exec_entry p1_entry, with
CMD exec_cmd p1_cmdentry. I get
/bin/sh -c exec_entry p1_entry sh -c exec_cmd p1_cmd
Answer questions jf
It's either that the table has to be changed.. or the statement that
The shell form prevents any CMD or run command line arguments from being used, ...has to be changed.
@StefanScherer can you confirm which is correct?
