Red Hat Bugzilla – Bug 1223547
When a command cannot be found in a Docker container the error displayed complains about HTTP error code
Last modified: 2016-07-27 07:17:34 EDT
Created attachment 1027854 [details] Error message displayed in the ui Description of problem: The attached screenshot shows that when the command that you pass to a Docker container cannot be found, an error complaining about the HTTP error code returned is displayed. This is not very useful because the real issue, the fact that the command passed cannot be found, is not being passed on to the user. Version-Release number of selected component (if applicable): * Satellite 6.1 GA SNAP 5 How reproducible: Steps to Reproduce: 1. Try to provision a new Docker container 2. Pass a made up command (i.e. zebra) to the container 3. Actual results: The UI displays the error: "Error - Expected([200, 201, 202, 203, 204, 304]) <=> Actual(404 Not Found)" Expected results: The UI should inform the user that the command was not found (equivalent to what you'd get if you were to run docker start on the container itself; see below) Additional info: [root@ibm-x3250m4-03 ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES c70697875e53 registry.access.redhat.com:443/rhel7:latest "/usr/bin/top" 8 minutes ago docker-rhel7-1 d912c458943b centos:7 "/bin/bash" 29 minutes ago Up 15 minutes partha-test 7e5527c77e1a registry.access.redhat.com:443/rhel7.0:latest "/usr/bin/top" About an hour ago docker-rhel70-1 d9cb731b1d4f mongo:latest "/usr/bin/top" About an hour ago docker-mongo-1 4bf9e9e96ab9 registry.access.redhat.com:443/rhel7.1:latest "top" About an hour ago docker-rhel71-1 b1c243a74c82 ibm-x3250m4-03.lab.eng.rdu2.redhat.com:5000/default_organization-dockerproduct-centos:7 "top" About an hour ago Up 10 minutes docker-centos-1 [root@ibm-x3250m4-03 ~]# docker start c70697875e53Error response from daemon: Cannot start container c70697875e53: [8] System error: exec: "/usr/bin/top": stat /usr/bin/top: no such file or directory FATA[0000] Error: failed to start one or more containers
Can you try this out again? When I try to reproduce this and create a container with a made up command, I see this error (using the hub in case that mattered): Error: Error - Cannot start container 7eca005cbe885a04a728f1a6a88978db2d745fd97b876fe77c3095d01486060d: [8] System error: exec: "zebra": executable file not found in $PATH I'm guessing that 404 came from the Docker API, and now it returns the full error so that's why it now displays the proper text

VERIFIED. @satellite-6.2.0-15.1.beta.el7sat.noarch I created a container with non-existent command 'zebra' and upon running it I get popup with relevant error msg (x) Error: Error - Cannot start container d9e2621f1b3dce1298ba4e878cbb6952c89179332d05d75137afc518522ee056: [8] System error: exec: "zebra": executable file not found in $PATH
