Docker container for syncing trusty and xenial ubuntu LTS mirrors
|
|
|
|
|
to reduce network traffic and speed up build times.
|
|
|
|
|
|
|
|
|
|
I recommend deploying this with a `--dns 172.17.0.1` in your
|
|
|
|
|
`/etc/default/docker` and dnsmasq bound to 172.17.0.1:53 to rewrite
|
|
|
|
|
`archive.ubuntu.com` to `172.17.0.1` (which this image will be listening and
|
|
|
|
|
serving on).
|
|
|
|
|
|
|
|
|
|
Then even your builds (where you can't specify links) will go fast.

* `MIRROR_CATEGORIES`
|
|
|
|

|
|
|
|
|
* You may want `main,universe,restricted,multiverse`. Will use lots of
|
|
|
|
|
disk.

|
|
|
|
|

# Example dnsmasq setup
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
apt-get update && apt-get -y install dnsmasq
|
|
|
|
|
cat > /etc/dnsmasq.d/docker <<EOF
|
|
|
|
|
no-resolv
|
|
|
|
|
server=8.8.8.8
|
|
|
|
|
server=8.8.4.4
|
|
|
|
|
EOF
|
|
|
|
|
echo "172.17.0.1 archive.ubuntu.com" >> /etc/hosts
|
|
|
|
|
service dnsmasq restart
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Then, just add `--dns 172.17.0.1` to your /etc/default/docker opts
|
|
|
|
|
and bounce the docker daemon. Future containers will talk to your local
|
|
|
|
|
mirror.
