Miroslav we should continue to run docker as a permissive domain, or even unconfined_domain for now. Too many unkowns. 25b7c9d4566df5b2ac5ec731dc5a4047822446f9 fixes this in git. commit 25b7c9d4566df5b2ac5ec731dc5a4047822446f9

Description of problem: Tried to set up the fedora/memcached:latest docker image through Cockpit. SELinux is preventing /usr/bin/docker from using the 'setfcap' capabilities. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that docker should have the setfcap 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 /usr/bin/docker Port <Unknown> Host (removed) Source RPM Packages docker-io-1.1.2-2.fc21.x86_64 Target RPM Packages Policy RPM selinux-policy-3.13.1-67.fc21.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.16.0-0.rc6.git3.1.fc21.x86_64 #1 SMP Sat Jul 26 13:57:52 UTC 2014 x86_64 x86_64 Alert Count 2 First Seen 2014-08-06 10:33:24 CEST Last Seen 2014-08-06 10:33:41 CEST Local ID 17d2fb67-32bf-42f6-a4d7-1d61f3cbbff1 Raw Audit Messages type=AVC msg=audit(1407314021.608:1083): avc: denied { setfcap } for pid=5072 comm="docker" capability=31 scontext=system_u:system_r:docker_t:s0 tcontext=system_u:system_r:docker_t:s0 tclass=capability permissive=1 type=SYSCALL msg=audit(1407314021.608:1083): arch=x86_64 syscall=lsetxattr success=yes exit=0 a0=c2085a4300 a1=c208460180 a2=c208460160 a3=14 items=0 ppid=1 pid=5072 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=docker exe=/usr/bin/docker subj=system_u:system_r:docker_t:s0 key=(null) Hash: docker,docker_t,docker_t,capability,setfcap Version-Release number of selected component: selinux-policy-3.13.1-67.fc21.noarch Additional info: reporter: libreport-2.2.3 hashmarkername: setroubleshoot kernel: 3.16.0-0.rc6.git3.1.fc21.x86_64 type: libreport
