If problems still persist, please make note of it in this bug report. |
Description of problem: Ran an image in a Docker container. Went back to command line and typed 'docker stop' on the container. SELinux threw an error. SELinux is preventing docker from using the 'kill' capabilities. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that docker should have the kill capability by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # grep docker /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:docker_t:s0 Target Context system_u:system_r:docker_t:s0 Target Objects Unknown [ capability ] Source docker Source Path docker Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-92.fc21.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.17.1-302.fc21.x86_64 #1 SMP Fri Oct 17 20:05:46 UTC 2014 x86_64 x86_64 Alert Count 8 First Seen 2014-11-02 22:15:39 PST Last Seen 2014-11-03 21:43:33 PST Local ID a88b000b-7ecc-4132-86a8-ee8ef94a1fd7 Raw Audit Messages type=AVC msg=audit(1415079813.677:1944): avc: denied { kill } for pid=2623 comm="docker" capability=5 scontext=system_u:system_r:docker_t:s0 tcontext=system_u:system_r:docker_t:s0 tclass=capability permissive=1 Hash: docker,docker_t,docker_t,capability,kill Version-Release number of selected component: selinux-policy-3.13.1-92.fc21.noarch Additional info: reporter: libreport-2.3.0 hashmarkername: setroubleshoot kernel: 3.17.1-302.fc21.x86_64 type: libreport
