First of all install update and upgrade your system:
$ sudo apt-get update
$ sudo apt-get upgrade
Then, install required libraries:
Just plug in your own values for registry and repo/image name.
registry='localhost:5000'
name='my-image'
curl -v -sSL -X DELETE "http://${registry}/v2/${name}/manifests/$(
curl -sSL -I \
-H "Accept: application/vnd.docker.distribution.manifest.v2+json" \
# 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 && \ | |
mount -t tmpfs tmpfs /tmp/overlay && \ | |
mkdir -p /tmp/overlay/{upper,work} && \ | |
mkdir -p /root/folder && \ |
Docker provides download links in release note. They promised that
(we) will also include download links in release notes for future releases.
Note:

coroutine1 = do_some_work(1) | |
coroutine2 = do_some_work(2) | |
coroutine3 = do_some_work(4) | |
tasks = [ | |

asyncio.ensure_future(coroutine3) | |

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。
什么用 S6 而不是 Supervisor?
Let's say you have a SysV Init Script
named foo
Copy the file to /etc/init.d/foo
Enable the SysV service: chkconfig --add foo
Enable the SysV service: chkconfig foo on
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
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)
[Install]

GNOME's tracker is a CPU and privacy hog. There's a pretty good case as to why it's neither useful nor necessary here: http://lduros.net/posts/tracker-sucks-thanks-tracker/
After discovering it chowing 2 cores, I decided to go about disabling it.
