我尝试了 `./launcher stop app` 然后 `./launcher start app --docker-args --memory="1g"`，但它似乎没有将 `--memory="1g"` 传递给 docker，因为 `docker stats` 仍然显示 LIMIT = 机器的所有 RAM。
我错过了什么吗？是否有预先记录的 docker 映像的启动命令（带标志）——我看到 launcher 脚本只是执行 `docker start app`？我不是 docker 专家。
附注：以 `bash -x launcher start app --memory="1g"` 运行显示测试命令确实带有 --memory=1g 标志，但 docker start 命令没有，它只是纯粹的 `docker start app`：
```plaintext
+ case "${1}" in
+ user_args_argv=--memory=1g
+ user_args=--memory=1g
+ shift
++ /usr/bin/docker run --memory=1g -i --rm -a stdout -a stderr discourse/base:2.0.20231004-0028 echo working
+ test=working
+ [[working =~ working]]
+ :
+ echo 'starting up existing container'
starting up existing container
+ set -x
+ /usr/bin/docker start app
app
+ exit 0
```

我刚才遇到了一个问题，我认为你需要让 `--docker-args` 生效，需要加一些引号。
例如：
```plaintext
./launcher rebuild app --docker-args '--privileged'
```
对我来说，这确实会将 `--privileged` 传递给 docker。
