Docker configuration Cache Proxy service Apt-cacher-ng

Apt-cacher-ng is a caching proxy service (or apt proxy) for Debian-based devices such as Ubuntu, Kubuntu, Xubuntu, Edubuntu, Linux mint, etc., which is used to cache packages that have already been downloaded.

You have a few computers linked to the network, you want to manually install or update the package on each machine, (imagine) this is a rather difficult task and time-consuming; that's why we have to configure a Apt-cacher-ng service to all systems this great idea, Since it will cache all downloaded packages from the network for the first time to Apt-cache server, the remaining Debian, Ubuntu machines get these packages just from Apt-cache directly, which will save us valuable time and network bandwidth.

Characteristics

1. Apt-cacher-ng will save us time.

2. Apt-cacher-ng will save our bandwidth.

3. By importing the parameters, we can integrate the ISO image data or DVD to Apt-cacher-ng.

This experiment uses Docker containers to build:

1, first create the Dockerfile file,

[Email protected]:~/docker/apt-cache-ng# cat Dockerfile from Ubuntuvolume ["/var/cache/apt-cacher-ng"]run Apt-get update && apt-get install-y apt-cacher-ngexpose 3142CMD chmod 777/var/cache/apt-cacher-ng & &/etc/init.d/apt-cacher-ng start && tail-f/var/log/apt-cacher-ng/*

2. Build this image

Docker build-t Eg_apt_cache_ng.

3. Boot the image and map the port to 13142 on the host

Docker run-d-P 13142:3142--name test_apt_cacher_ng eg_apt_cacher_ng

4. You can use the Docker command to view the log

Docker Logs-f Test_apt_cacher_ng

Here, we can see the Apt-cacher-ng report page, click on the static report, configure the bottom of the page, navigate to the download hit or error situation page.

On the report page we need to copy the proxy URL for use behind. We can install packages on this server, by configuring local parameters, adding entity/etc/apt/apt.conf.d/02proxy apt-cache.

acquire::http {Proxy "http://192.168.0.2:3142";};

Description of the Docker website:

to Get your debian-based containers to use the proxy and you have following options. Note that you must replace test_apt_cacher_ng  container.

2. Add an apt Proxy settingecho ‘Acquire::http { Proxy "http://dockerhost:3142"; };‘ >> /etc/apt/conf.d/01proxy

4. Set an environment variable:http_proxy=http://dockerhost:3142/

6. Change your sources.list entries to start withhttp://dockerhost:3142/

8. Link debian-based containers to the APT proxy container using--link

10. Create a custom network of a APT proxy container with debian-based containers.

6. Create a Docker container for the client

Docker run--rm-t-i-e Http_proxy=http://192.168.0.2:3142/debian bash

You can also use Dockerfile to specify

From Ubunturun Echo ' acquire::http {Proxy "http://192.168.0.2:3142";}; ' >>/etc/apt/apt.conf.d/01proxyrun Apt-ge T update && apt-get install-y vim git

Link container to apt container

Docker run-i-T--link test_apt_cacher_ng:apt_proxy-e Http_proxy=http://apt_proxy:3142/debian Bash

You can also create a container yourself and then go into the container to manually configure

Vim/etc/apt/apt.conf.d/02proxy #在这个路径下创建文件 acquire::http {Proxy "http://192.168.0.2:3142";}; #写入这条内容

7. Test:

All over our server and client are installed.

Log in to the client, go to update several packages, or install a few packages, and then the Web can see how many files are cached

Here you can put the installation package, uninstall, and then install again, you will find that the speed will be very fast, and the web will be hits will also have a change to show whether you download from apt
