This is same "docker ps hangs #18013".
For some reason, Processing seems to stop in the following part. $ strace docker ps >& docker.txt

$ tail -f docker.txt
setsockopt(3, SOL_SOCKET, SO_BROADCAST, [1], 4) = 0
connect(3, {sa_family=AF_LOCAL, sun_path="/var/run/docker.sock"}, 23) = 0
epoll_create1(EPOLL_CLOEXEC)            = 4
epoll_ctl(4, EPOLL_CTL_ADD, 3, {EPOLLIN|EPOLLOUT|EPOLLRDHUP|EPOLLET, {u32=1052296288, u64=139750698173536}}) = 0
getsockname(3, {sa_family=AF_LOCAL, NULL}, [2]) = 0
getpeername(3, {sa_family=AF_LOCAL, sun_path="/var/run/docker.sock"}, [23]) = 0
read(3, 0xc208512000, 4096)             = -1 EAGAIN (Resource temporarily unavailable)
