Issue Description
Type: help wanted

Describe what happened (or what feature you want)

First:
Though I read issue #12, I still can't understand.
I haven't pull docker image registry.cn-hangzhou.aliyuncs.com/chaosblade/chaosblade-agent:0.0.3 or other version. When I run
./blade create docker cpu fullload --container 4c5c3a7706ec --numcpu 8 on the Ubuntu system ,it return {"code":200,"success":true,"result":"83484e440a710e46"} .
But when I run on the Centos system, it return ******no such container .

Second:
When create docker cpu fullload failed on the Centos System, I pull the images "registry.cn-hangzhou.aliyuncs.com/chaosblade/chaosblade-agent:0.0.3" , and run "docker run -d -t --pid container:4c5c3a7706ec --ipc container:4c5c3a7706ec --name 4c5c3a7706ec-cpu sh -c /usr/local/chaosblade/bin/chaos_burncpu --start " , it return "docker: --pid:invalid PID mode". Where is my mistake?
