Adopt Black and isort (SC-700) (#1157)

2021-12-16T02:16:38+00:00

Applied Black and isort, fixed any linting issues, updated tox.ini and CI.

Add new network activators to bring up interfaces (#919)

2021-07-01T19:43:07+00:00

Currently _bring_up_interfaces() is a no-op for any distro using renderers. We need to be able to support bringing up a single interfaces, a list of interfaces, and all interfaces. This should be independent of the renderers, as the network config is often generated independent of the mechanism used to apply it. Additionally, I included a refactor to remove "_supported_write_network_config". We had a confusing call chain of apply_network_config->_write_network_config->_supported_write_network_config. The last two have been combined.

Move subp into its own module. (#416)

2020-06-08T16:49:12+00:00

This was painful, but it finishes a TODO from cloudinit/subp.py. It moves the following from util to subp: ProcessExecutionError subp which target_path I moved subp_blob_in_tempfile into cc_chef, which is its only caller. That saved us from having to deal with it using write_file and temp_utils from subp (which does not import any cloudinit things now). It is arguable that 'target_path' could be moved to a 'path_utils' or something, but in order to use it from subp and also from utils, we had to get it out of utils.

net: fix rendering of 'static6' in network config (#77)

2020-01-08T17:30:17+00:00

* net: fix rendering of 'static6' in network config A V1 static6 network typo was misrendered in eni, it's not valid. It was ignored in sysconfig and netplan. This branch fixes eni, updates sysconfig, netplan to render it correctly and adds unittests for all cases.

net: IPv6, accept_ra, slaac, stateless (#51)

2019-11-20T17:55:26+00:00

Router advertisements are required for the default route to be set up, thus accept_ra should be enabled for dhcpv6-stateful. sysconf: IPV6_FORCE_ACCEPT_RA controls accept_ra sysctl. eni: mode static and mode dhcp 'accept_ra' controls sysctl. Add 'accept-ra: true|false' parameter to config v1 and v2. When True: accept_ra is set to '1'. When False: accept_ra is set to '0'. When not defined in config the value is left to the operating system default. This change also extend the IPv6 support to distinguish between slaac and dhcpv6-stateless. SLAAC is autoconfig without any options from DHCP, while stateless auto-configures the address and the uses DHCP for other options. LP: #1806014 LP: #1808647

net/netplan: use ipv6-mtu key for specifying ipv6 mtu values

2019-10-24T20:16:47+00:00

netplan introduced an 'info' subcommand which emits yaml describing implemented features that indicate new or changed fields and values in the yaml that it accepts. Previously, cloud-init emitted the key 'mtu6' for ipv6 MTU values. This is not correct and netplan will fail to parse these values. Netplan as of 0.98 supports both the info subcommand and the ipv6-mtu key. This branch modifies the netplan renderer to collect the netplan info output into a 'features' property which is a list of available feature flags which the renderer can use to modify its output. If the command is not available, no feature flags are set and cloud-init will render IPv6 MTU values just as MTU for the subnet.

Fix usages of yaml, and move yaml_dump to safeyaml.dumps.

2019-10-24T20:02:15+00:00

Here we replace uses of the pyyaml module directly with functions provided by cloudinit.safeyaml. Also, change/move cloudinit.util.yaml_dumps to cloudinit.safeyaml.dumps LP: #1849640

netplan: Don't render yaml aliases when dumping netplan

2019-02-07T22:38:41+00:00

Cloud-init rendered netplan with duplicate aliases if a network config included "global" nameserver/search values. Netplan uses can read yaml files which do use aliaes but cloud-init did not render a single yaml dictionary, instead it combined yaml sections into a single document which sometimes resulted in duplicate aliases being present. This branch introduces a yaml SafeDumper class which can set the 'ignore_aliases' attribute. This is not enabled by default but callers to util.yaml_dumps can pass a boolean to toggle this. The netplan render uses noalias=True and the resulting yaml output does not contain any aliases. LP: #1815051

net: render 'metric' values in per-subnet routes

2018-12-11T17:24:11+00:00

It is possible to have a metric value in a per-subnet route. This is currently missing in all renderers. Update each renderer to emit the correct metric value from the config. LP: #1805871

sysconfig: refactor sysconfig to accept distro specific templates paths

2018-09-05T14:17:16+00:00

Multiple distros use sysconfig format but have different content and paths to certain files. Update distros to specify these template paths in their renderer_configs dictionary.
