Introduction

These images are designed for mirroring remote directories/repositories in a consistent and portable way. They are used by ustcmirror (yuki).

Quick Start

docker run --rm \
    -e LOG_ROTATE_CYCLE='5' \
    -e RSYNC_HOST='rsync.alpinelinux.org' \
    -e RSYNC_PATH='alpine/' \
    -e RSYNC_MAXDELETE='10000' \
    -v /var/repos/alpine:/data \
    -v /var/sync-logs/alpine:/log \
    ustcmirror/rsync:latest

Configuration

Volumes

• /data: The mount point of the repository on the host. You can refer to it as environment variable TO in your program.
• /log: The mount point of the host directory that save logs. You can refer to it as environment variable LOG in your program.

Common Configuration Parameters(AKA environment variables)

Parameter	Description
DEBUG	Set this to true to enable debugging.
BIND_ADDRESS	Set the local ip to be bound. Require --network=host. (Some programs don't support this parameter)
OWNER	Set the uid and gid of the process so that the downloaded files wont get messed up. Defaults to 0:0 (aka root:root).
LOG_ROTATE_CYCLE	Specify how many cycle versions of the logfile to be saved. Set this to 0 will disable rotation. Defaults to 0.
REPO	Name of the repository. Required in archvsync.
RETRY	Times to re-sync if the process exits abnormally. Defaults to 0.

aptsync

Parameter	Description
APTSYNC_URL	Sets the url of upstream.
APTSYNC_NTHREADS	Defaults to 20.
APTSYNC_UNLINK	Set this to 1 to remove unneeded files automatically. Defaults to 0.
APTSYNC_CREATE_DIR	Set this to true to create same directory tree as upstream URL. Defaults to true.
APTSYNC_DISTS	Various distros can be specified in the format <release> [...]|<componenet> [...]|<arch> [...][:...].

Notes: The following mirror.list:

deb-i386 https://apt.dockerproject.org/repo debian-jessie main
deb-amd64 https://apt.dockerproject.org/repo debian-jessie main
deb-armhf https://apt.dockerproject.org/repo raspbian-jessie main testing

is equivalent to the following parameters:

APTSYNC_URL='https://apt.dockerproject.org/repo'
APTSYNC_DISTS='debian-jessie|main|i386 amd64:raspbian-jessie|main testing|armhf'

apt-sync

Parameter	Description
APTSYNC_URL	Sets the url of upstream.
APTSYNC_UNLINK	Set this to 1 to remove unneeded files automatically. Defaults to 0.
APTSYNC_DISTS	Various distros can be specified in the format <release> [...]|<componenet> [...]|<arch> [...]|<download_dir> [...][:...].

It is almost the same as aptsync. Except that APTSYNC_DISTS accepts 4 parameters (rather than 3) for every item.

Consider use apt-sync when the upstream replaces packages in-place, as aptsync will simply ignore if there're any changes in existed packages.

Read the user guide before writing preferred mirror to config

YUMSYNC_DOWNLOAD_REPODATA	Whether to download repodata files instead of generating them by createrepo

yum-sync tries to imitate the parameters of aptsync, and it supports the following substitution rule for YUMSYNC_URL and <reponame> & <download_dir> in YUMSYNC_DISTS:

• @{arch}: Architecture (x86_64, armhf, ...)
• @{os_ver}: OS version (6-8, ...)
• @{comp}: The <component> in YUMSYNC_DISTS

yum-sync.py is modified to get the same directory structure as upstream when syncing. And <reponame> should be named the same as the directory containing repodata dir.

Notes:

The following repo configuration:

baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el$releasever-$basearch

translates to:

YUMSYNC_URL='https://packages.cloud.google.com/yum/repos/kubernetes-el@{os_ver}-@{arch}'
YUMSYNC_DISTS='6-7|kubernetes|x86_64,aarch64,armhfp,ppc64le,s390x|kubernetes-el@{os_ver}-@{arch}|/yum/repos/kubernetes-el@{os_ver}-@{arch}'

And the following:

[mysql80-community]
name=MySQL 8.0 Community Server
baseurl=http://repo.mysql.com/yum/mysql-8.0-community/el/$releasever/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

[mysql57-community]
name=MySQL 5.7 Community Server
baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/$releasever/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

translates to:

YUMSYNC_URL='https://repo.mysql.com/yum/@{comp}/el/@{os_ver}/@{arch}/'
YUMSYNC_DISTS='6-8|mysql-8.0-community,mysql-5.7-community|aarch64,i386,x86_64|@{arch}|/yum/@{comp}/el/@{os_ver}/@{arch}/'
