     5  #### **--shm-size**=*number[unit]*
     6  
     7  Size of _/dev/shm_. A _unit_ can be **b** (bytes), **k** (kibibytes), **m** (mebibytes), or **g** (gibibytes).
     8  If the unit is omitted, the system uses bytes. If the size is omitted, the default is **64m**.
     9  When _size_ is **0**, there is no limit on the amount of memory used for IPC by the <<container|pod>>.
    10  This option conflicts with **--ipc=host**.
