如果 Docker 是一个应用程序容器（不像像 LxC 这样的系统容器），并且只用于运行一个应用程序/服务，我想知道一个完整的 Docker OS 容器对 Ubuntu 有什么好处？

例如，您更喜欢 Ubuntu Docker 容器而不是 Ubuntu LxC 容器的任何一个用例？

docker container

我正在尝试使用 docker、letsencrypt 和 traefik 设置一个家庭自动化服务器。还使用 duckdns 作为 ddns。我在同一台机器上还有一些其他容器，如 sickrage 等。

我已经打开并将路由器上的端口 80 和 443 转发到我的 ubuntu 18.04 服务器。当我尝试通过 http 连接到 sickrage.myserver.duckdns.org 时，出现以下错误：

**Your connection is not private**
Attackers might be trying to steal your information from sabnzbd.myserver.duckdns.org 
NET::ERR_CERT_AUTHORITY_INVALID

这是我的 traefik.toml 文件：

    logLevel = "WARN" #DEBUG, INFO, WARN, ERROR, FATAL, PANIC
defaultEntryPoints = ["http", "https"]

# WEB interface of Traefik - it will show web page with overview of frontend and backend configurations 
[api]
  entryPoint = "traefik"
  dashboard = true
  address = ":8080"

# Force HTTPS
[entryPoints]
  [entryPoints.http]
  address = ":80"
    [entryPoints.http.redirect]
     entryPoint = "https"
  [entryPoints.https]
  address = ":443"
    [entryPoints.https.tls]

[retry]


[file]
  watch = true
  filename = "${USERDIR}/docker/traefik/rules.toml"

# Let's encrypt configura
[acme]
caServer = "https://acme-v02.api.letsencrypt.org/directory"
email = "[email protected]"     #any email id will work
storage="${USERDIR}/docker/traefik/acme/acme.json"
entryPoint = "https"
acmeLogging=true 
onDemand = false #create certificate when container is created
onHostRule = true
  # Use a HTTP-01 acme challenge rather than TLS-SNI-01 challenge
  # uncomment 2 lines for subdirs
#[acme.httpChallenge]
[acme.dnsChallenge]
provider = "duckdns"
entryPoint = "https"
  # uncomment follwoing for suubsomains
#[[acme.domains]]
  #main = "myserver.duckdns.org"
#[[acme.domains]]
  #main = "*.myserver.duckdns.org"
#[acme.dnsChallenge]
  #provider = "duckdns"
  #delayBeforeCheck = 0

# Connection to docker host system (docker.sock)
[docker]
endpoint = "unix:///var/run/docker.sock"
domain = "myserver.duckdns.org"
watch = true
# This will hide all docker containers that don't have explicitly  
# set label to "enable"
exposedbydefault = false

以及我的 docker-compose 文件的一部分：

我尝试遵循的示例不包括 letsencrypt 容器。我应该删除它吗？如果是这样，letsencrypt 将如何跟踪停止和启动的容器？还有另一种方法可以让它运行吗？
