# On the host to run the container
docker run --privileged -i -t -v ~/host-folder-to-mount:/root/folder-ro:ro ubuntu

# Inside the container
# Need to create the upper and work dirs inside a tmpfs.
# Otherwise OverlayFS complains about AUFS folders. 
mkdir -p /tmp/overlay && \

Deprecated

Docker provides download links in release note. They promised that

(we) will also include download links in release notes for future releases.

【译】Docker 和 S6 ——我的进程管理器新欢

点击这里阅读原文。

---

在我之前的博文中，我描述了我是如何在容器中使用进程管理器的，并做了一些展开。但我还是觉得有必要针对 Laurent Bercot 开发的 S6 做更详尽的说明。

Let's say you have a SysV Init Script named foo

1. Copy the file to /etc/init.d/foo

2. Enable the SysV service: chkconfig --add foo

3. Enable the SysV service: chkconfig foo on

4. Start the service: service foo start. After this, systemd-sysv-generator will generate this file /run/systemd/generator.late/foo.service, copy this file to /etc/systemd/system by running: cp /run/systemd/generator.late/foo.service /etc/systemd/system/foo.service

5. Edit /etc/systemd/system/foo.service by running systemctl edit foo.service, add in the following line to foo.servie (this makes the service installable)
