增加 docker 内存以在 linux 上安装哨兵服务器

Question

我正在尝试在我的 linux 上安装哨兵 docker。克隆后它的存储库：

git clone https://github.com/getsentry/onpremise

我运行这个

$ ./install.sh

但是我得到了这个错误：

alt@mx-alt:/mnt/Software/Linux/sentry/onpremise
$ ./install.sh 
Checking minimum requirements...
FAIL: Expected minimum RAM available to Docker to be 2400 MB but found  MB

这是我的 docker 信息：

我写下我的回答可能对某人有帮助！

1 - 我先拉 busybox:

$ docker pull  busybox 
Using default tag: latest
latest: Pulling from library/busybox

alt@mx-alt:~
$ sudo docker run --rm busybox free -m 2
              total        used        free      shared  buff/cache   available
