Error when run docker-compose up -d

[thanhpd56]

Hi,
I got this error when run hub container:
[APP-WRAPPER] Failed to configure Hub: java.util.concurrent.ExecutionException: com.jetbrains.service.util.StatusException: Native random generator does not seem to have enough entropy for JetBrains Hub 2018.1 to start.
You can fix it by switching to PRNG (with -Djava.security.egd=/dev/zrandom) or by reconfiguring your operation system to provide more random bits.
My VPS:

• Centos 7
• MEM: 4GB
  Any suggestion?
  Thanks in advance.
