# apt_pipelining (configure Acquire::http::Pipeline-Depth)
# Default: disables HTTP pipelining. Certain web servers, such
# as S3 do not pipeline properly (LP: #948461).
# Valid options:
#   False/default: Disables pipelining for APT
#   None/Unchanged: Use OS default
#   Number: Set pipelining to some number (not recommended)
apt_pipelining: False

## apt config via system_info:
# under the 'system_info', you can customize cloud-init's interaction
# with apt.
#  system_info:
#    apt_get_command: [command, argument, argument]
#    apt_get_upgrade_subcommand: dist-upgrade
#
# apt_get_command:
#  To specify a different 'apt-get' command, set 'apt_get_command'.
#  This must be a list, and the subcommand (update, upgrade) is appended to it.
#  default is:
#    ['apt-get', '--option=Dpkg::Options::=--force-confold',
#     '--option=Dpkg::options::=--force-unsafe-io', '--assume-yes', '--quiet']
#
# apt_get_upgrade_subcommand: "dist-upgrade"
#  Specify a different subcommand for 'upgrade. The default is 'dist-upgrade'.
#  This is the subcommand that is invoked for package_upgrade.
#
# apt_get_wrapper:
#   command: eatmydata
#   enabled: [True, False, "auto"]
#

# Install additional packages on first boot
#
# Default: none
#
# if packages are specified, this apt_update will be set to true

packages: ['pastebinit']

apt:
  # The apt config consists of two major "areas".
  #
  # On one hand there is the global configuration for the apt feature.
  #
  # On one hand (down in this file) there is the source dictionary which allows
  # to define various entries to be considered by apt.

##############################################################################
  # Section 1: global apt configuration
  #
  # The following examples number the top keys to ease identification in
  # discussions.

# 1.1 preserve_sources_list
  #
  # Preserves the existing /etc/apt/sources.list
  # Default: false - do overwrite sources_list. If set to true then any
  # "mirrors" configuration will have no effect.
  # Set to true to avoid affecting sources.list. In that case only
  # "extra" source specifications will be written into
  # /etc/apt/sources.list.d/*
  preserve_sources_list: true

# 1.2 disable_suites
  #
  # This is an empty list by default, so nothing is disabled.
  #
  # If given, those suites are removed from sources.list after all other
  # modifications have been made.
  # Suites are even disabled if no other modification was made,
  # but not if is preserve_sources_list is active.
  # There is a special alias "$RELEASE" as in the sources that will be replace
  # by the matching release.
  #
  # To ease configuration and improve readability the following common ubuntu
  # suites will be automatically mapped to their full definition.
  # updates   => $RELEASE-updates
  # backports => $RELEASE-backports
  # security  => $RELEASE-security
  # proposed  => $RELEASE-proposed
  # release   => $RELEASE
  #
  # There is no harm in specifying a suite to be disabled that is not found in
  # the source.list file (just a no-op then)
  #
  # Note: Lines don't get deleted, but disabled by being converted to a comment.
  # The following example disables all usual defaults except $RELEASE-security.
  # On top it disables a custom suite called "mysuite"
  disable_suites: [$RELEASE-updates, backports, $RELEASE, mysuite]

# 1.3 primary/security archives
  #
  # Default: none - instead it is auto select based on cloud metadata
  # so if neither "uri" nor "search", nor "search_dns" is set (the default)
  # then use the mirror provided by the DataSource found.
  # In EC2, that means using <region>.ec2.archive.ubuntu.com
  #
  # define a custom (e.g. localized) mirror that will be used in sources.list
  # and any custom sources entries for deb / deb-src lines.
  #
  # One can set primary and security mirror to different uri's
  # the child elements to the keys primary and secondary are equivalent
  primary:
    # arches is list of architectures the following config applies to
    # the special keyword "default" applies to any architecture not explicitly
    # listed.
    - arches: [amd64, i386, default]
      # uri is just defining the target as-is
      uri: http://us.archive.ubuntu.com/ubuntu
      #
      # via search one can define lists that are tried one by one.
      # The first with a working DNS resolution (or if it is an IP) will be
      # picked. That way one can keep one configuration for multiple
      # subenvironments that select the working one.
      search:
        - http://cool.but-sometimes-unreachable.com/ubuntu
        - http://us.archive.ubuntu.com/ubuntu
      # if no mirror is provided by uri or search but 'search_dns' is
      # true, then search for dns names '<distro>-mirror' in each of
      # - fqdn of this host per cloud metadata
      # - localdomain
      # - no domain (which would search domains listed in /etc/resolv.conf)
      # If there is a dns entry for <distro>-mirror, then it is assumed that
      # there is a distro mirror at http://<distro>-mirror.<domain>/<distro>
      #
      # That gives the cloud provider the opportunity to set mirrors of a distro
      # up and expose them only by creating dns entries.
      #
      # if none of that is found, then the default distro mirror is used
      search_dns: true
      #
      # If multiple of a category are given
      #   1. uri
      #   2. search
      #   3. search_dns
      # the first defining a valid mirror wins (in the order as defined here,
      # not the order as listed in the config).
      #
    - arches: [s390x, arm64]
      # as above, allowing to have one config for different per arch mirrors
  # security is optional, if not defined it is set to the same value as primary
  security:
      uri: http://security.ubuntu.com/ubuntu
  # If search_dns is set for security the searched pattern is:
  #   <distro>-security-mirror

# if no mirrors are specified at all, or all lookups fail it will try
  # to get them from the cloud datasource and if those neither provide one fall
  # back to:
  #   primary: http://archive.ubuntu.com/ubuntu
  #   security: http://security.ubuntu.com/ubuntu

# 1.4 sources_list
  #
  # Provide a custom template for rendering sources.list
  # without one provided cloud-init uses builtin templates for
  # ubuntu and debian.
  # Within these sources.list templates you can use the following replacement
  # variables (all have sane Ubuntu defaults, but mirrors can be overwritten
  # as needed (see above)):
  # => $RELEASE, $MIRROR, $PRIMARY, $SECURITY
  sources_list: | # written by cloud-init custom template
    deb $MIRROR $RELEASE main restricted
    deb-src $MIRROR $RELEASE main restricted
    deb $PRIMARY $RELEASE universe restricted
    deb $SECURITY $RELEASE-security multiverse

# 1.5 conf
  #
  # Any apt config string that will be made available to apt
  # see the APT.CONF(5) man page for details what can be specified
  conf: | # APT config
    APT {
      Get {
        Assume-Yes "true";
        Fix-Broken "true";
      };
    };

# 1.6 (http_|ftp_|https_)proxy
  #
  # Proxies are the most common apt.conf option, so that for simplified use
  # there is a shortcut for those. Those get automatically translated into the
  # correct Acquire::*::Proxy statements.
  #
  # note: proxy actually being a short synonym to http_proxy
  proxy: http://[[user][:pass]@]host[:port]/
  http_proxy: http://[[user][:pass]@]host[:port]/
  ftp_proxy: ftp://[[user][:pass]@]host[:port]/
  https_proxy: https://[[user][:pass]@]host[:port]/

# 1.7 add_apt_repo_match
  #
  # 'source' entries in apt-sources that match this python regex
  # expression will be passed to add-apt-repository
  # The following example is also the builtin default if nothing is specified
  add_apt_repo_match: '^[\w-]+:\w'

##############################################################################
  # Section 2: source list entries
  #
  # This is a dictionary (unlike most block/net which are lists)
  #
  # The key of each source entry is the filename and will be prepended by
  # /etc/apt/sources.list.d/ if it doesn't start with a '/'.
  # If it doesn't end with .list it will be appended so that apt picks up it's
  # configuration.
  #
  # Whenever there is no content to be written into such a file, the key is
  # not used as filename - yet it can still be used as index for merging
  # configuration.
  #
  # The values inside the entries consost of the following optional entries:
  #   'source': a sources.list entry (some variable replacements apply)
  #   'keyid': providing a key to import via shortid or fingerprint
  #   'key': providing a raw PGP key
  #   'keyserver': specify an alternate keyserver to pull keys from that
  #                were specified by keyid

# This allows merging between multiple input files than a list like:
  # cloud-config1
  # sources:
  #    s1: {'key': 'key1', 'source': 'source1'}
  # cloud-config2
  # sources:
  #    s2: {'key': 'key2'}
  #    s1: {'keyserver': 'foo'}
  # This would be merged to
  # sources:
  #    s1:
  #        keyserver: foo
  #        key: key1
  #        source: source1
  #    s2:
  #        key: key2
  #
  # The following examples number the subfeatures per sources entry to ease
  # identification in discussions.

    curtin-dev-ppa.list:
      # 2.1 source
      #
      # Creates a file in /etc/apt/sources.list.d/ for the sources list entry

      source: "deb http://ppa.launchpad.net/curtin-dev/test-archive/ubuntu xenial main"

# 2.2 keyid

      # this requires 'add-apt-repository'. This will create a file in
      # /etc/apt/sources.list.d automatically, therefore the key here is
      # ignored as filename in those cases.
      source: "ppa:curtin-dev/test-archive"    # Quote the string

my-repo2.list:
      # 2.4 replacement variables
      #
      # sources can use $MIRROR, $PRIMARY, $SECURITY and $RELEASE replacement
      # variables.
      # They will be replaced with the default or specified mirrors and the
      # running release.
      # The entry below would be possibly turned into:
      #   source: deb http://archive.ubuntu.com/ubuntu xenial multiverse
      source: deb $MIRROR $RELEASE multiverse

my-repo3.list:
      # this would have the same end effect as 'ppa:curtin-dev/test-archive'
      source: "deb http://ppa.launchpad.net/curtin-dev/test-archive/ubuntu xenial main"
      keyid: F430BBA5 # GPG key ID published on the key server
      filename: curtin-dev-ppa.list

ignored2:
      # 2.5 key only
      #
      # this would only import the key without adding a ppa or other source spec
      # since this doesn't generate a source.list file the filename key is ignored
      keyid: F430BBA5 # GPG key ID published on a key server

ignored3:
      # 2.6 key id alternatives
      #
      # Keyid's can also be specified via their long fingerprints
      keyid: B59D 5F15 97A5 04B7 E230  6DCA 0620 BBCF 0368 3F77

      keyserver: pgp.mit.edu

my-repo4.list:
      # 2.8 raw key
      #
      # The apt signing key can also be specified by providing a pgp public key
      # block. Providing the PGP key this way is the most robust method for
      # specifying a key, as it removes dependency on a remote key server.
      #
      # As with keyid's this can be specified with or without some actual source
      # content.
