Client Configuration

Using Ansible

You can set the apt proxy as a host variable:

[host:vars]
apt_proxy=http://apt.example.com:3142/

For the entire system:

- name: Set up apt proxy
  template: src=templates/apt_proxy.conf dest=/etc/apt/apt.conf.d/01proxy owner=root group=root mode=0644
    when: ansible_os_family == "Debian" and apt_proxy is defined

Template: templates/apt_proxy.conf:

# {{ ansible_managed }}
Acquire::http { Proxy "{{ apt_proxy }}"; };
Acquire::https { Proxy "https://"; };

For a single task:

- apt: name=ufw state=installed
  environment:
    http_proxy: "{{ apt_proxy }}"

Without Ansible

Make sure to replace the server IP or FQDN!

$ echo 'Acquire::http { Proxy "http://apt.example.com:3142"; };' > /etc/apt/apt.conf.d/01proxy

Importing Localhost Cache

$ echo 'Acquire::http { Proxy "http://localhost:3142"; };' > /etc/apt/apt.conf.d/01proxy
$ apt-get update
$ apt-get autoclean
$ mkdir -p /var/cache/apt-cacher-ng/_import
$ ln -s /var/cache/apt /var/cache/apt-cacher-ng/_import/apt
$ wget "http://localhost:3142/acng-report.html?abortOnErrors=aOe&doImport=Start+Import&calcSize=cs&asNeeded=an#bottom"

After the import, you can remove the symlink:

$ rm /var/cache/apt-cacher-ng/_import/apt
