An ansible role to configure networking

It seems to be supported in the code but it is not documented.
Currently, the role does the corresponding of nmcli con up
when it notices changes to the profile. If the profile already is active, this caues NM to first tear the device down, before reactivating it. This is more disruptive than desired. The Reapply
D-Bus command should be used where possible.
Note that with Reapply
, NetworkManager first checks whether it can perform the desired actions, and abort with failure if it cannot (without touching the system). Hence, a suitable way to do this, is first try to reapply, and if that fails, fall back to full activation.
Note also, how reapply changes the "applied-connection", and there is also a version-id, that allows to perform the reapply only, if the state is as expected.
Maybe older NM versions don't yet sufficiently support Reapply. It needs to be seen whether the role needs some special handling.
The role aims to accept the desired networking configuration in a declarative way. The user doesn't say to issue a certain command or series of steps (like nmcli
). Instead, the user describes the desired outcome in a declarative way, and the role makes it happen (depending on the configured provider
).
This is the case with the states present
and absent
. These states intend to only deploy persistent configuration on the host, but not actually changing the current networking configuration. Essentially they create/delete connection profiles in NetworkManager or write/delete ifcfg files. For these states, the order doesn't really matter (unless you specify the same profile more then once -- "same" in the sense of having the same name).
Then there are the states up
and down
, which basically translate to nmcli connection up|down
or ifup|ifdown
calls. For NetworkManager provider, the order in which you activate/deactivate a set of profiles shouldn't matter too much. NetworkManager should make it happen correctly, in either order. That might not be entirely true, for example if you activate a slave connection first or after the master, makes an actual difference. For initscripts, this is much more a problem though. The role doesn't really know what the current state of the system is, and neither do the initscripts. It essentially leaves the decision of getting the right order for calling ifup
to the user.
Currently, the order is the same as specified in the playbook. This should be improved. The user should just say which profiles should be up/down, and the role should figure out how to get that desired outcome (and in which order to call ifup/nmcli connection up
).
See also the variable force_state_change
. The role should become smarter about this, so that we require it less.

Currently there is no way via ansible to support device specific options set via ethtool command. This allows for setting a variety of NIC parameters from speed, duplex, variety offloads, and even buffers. modifying these values is critical to network performance in many enterprise environments, and thus would be good if linux-system-roles supported configuring them.
Originally reported by @hartsjc in #17 (comment)
Currently it accepts only an IP address and requires the prefix to contain the router mask.
I tested the role with initscripts network provider in CentOS 7.6.
If I change the ip->dns variable, /etc/resolv.conf is rewritten with the new dns values, but the dns_search value is always appended, never overwritten.
After a few executions of the role, here is the resulting resolv.conf
search domain.org domain.org domain.org domain.org domain.org
nameserver 192.168.121.2
nameserver 192.168.121.3
Moreover, it is a pity that using this role the diff feature of ansible does not work. It would be nice to see the changes applied to the configuration files.
Commonly, the role will connect to the host via SSH. Hence, it cannot currently support to change the IP address of the host, because it will cut itself off.
ansible supports reboot of the system or changing the TCP port of the SSH server via async requests and poll for completion. Something similar should be possible for the network role.
The user should be able to specify that the role works asynchronously, and that afterwards the host is reachable via a new IP address.
Also interesting is to combine this with the CheckPoint feature of NetworkManager.

Expected results:
It seems that when creating an interface, the default behavior is to also activate it. However, the expecation is that if "state: up" is specified, there should be no errors or warnings.
Instead of requiring bond slaves to be specified as individual profiles it might make sense to mention the members directly in the master configuration. This is also suggested here: https://bugzilla.redhat.com/show_bug.cgi?id=1508614#c4
Support for network scripts moved from initscipts to network-scripts
package. This needs to be installed for the appropriate systems.
When running a playbook a second time, it not detecting that the interface is already up and errors out.

Idea by @thom311 in #33 to use the checkpoint feature to revert changes in case the host cannot be reached anymore after the configuration. A possible idea would be not to remove the checkpoint but send it back to the ansible host and destroy it in a later step to test that the host can still be reached.
Many of the /etc/sysconfig/network-scripts/ifcfg- options documented in /usr/share/doc/initscripts-*/sysconfig.txt do not appear to be supported. Some key/crucial ones that appear to be missing for enterprise servers are:
1. ETHTOOL_OPTS
2. LINKDELAY
3. IPV4_FAILURE_FATAL
Some others may include (have not tested to validate missing, just grep of code):
ARPCHECK

DHCLIENT_IGNORE_GATEWAY

HOTPLUG

Happened on CentOS 7.
README.md currently uses the d6:06:b9:56:12:5d MAC address in an example. examples/inventory use the 52:54:00:44:9f:ba and 52:54:00:05:f5:b3 MAC addresses.
The examples under examples/ use the 192.168.174. network prefix.
Is there a special reason why those values were chosen? If not, it might be better to use the addresses which are reserved for use in documentation by IANA. For IP adresses those are the 192.0.2.0/24, 198.51.100.0/24 and 203.0.113.0/24 blocks (RFC 5735). For MAC adresses, this is the 00-00-5E-00-53-00 through 00-00-5E-00-53-FF block (RFC 7042).
Note that the firewall role uses example addresses as well, it would be good to agree on a common standard.
Wanting to switch from editing /etc/sysconfig/network-scripts/ifcfg-โฆ
I am wondering what the clean way to get
ETHTOOL_OPTS="wol g"
configured with linux-system-roles / network
The current README.md does not seem to contain either the string wol or the string wake.
Since enabling wake on LAN (p|u|m|b|a|g|s|f|d) is a rather common procedure, it would be nice if this was covered in the documentation of the module.
Many of the nmcli connection show options available do not appear to be supported. Even several of them that supported in nm-connection-editor don't appear to be present...
Doing a quick look think some examples are:
connection.lld
connection.autoconnect <-------------- in nm-connection-editor (general)
connection.autoconnect-priority <----- in nm-connection-editor (general)
connection.autoconnect-retries
connection.zone <--------------------- in nm-connection-editor (general)
802-3-ethernet.cloned-mac-address <--- in nm-connection-editor (ethernet)
802-3-ethernet.mtu <------------------ in nm-connection-editor (ethernet)
802-3-ethernet.wake-on-lan-password <- in nm-connection-editor (ethernet)
802-3-ethernet.auto-negotiate <------- in nm-connection-editor (ethernet)
802-3-ethernet.speed <---------------- in nm-connection-editor (ethernet)
802-3-ethernet.duplex <--------------- in nm-connection-editor (ethernet)
ipv4.may-fail <----------------------- in nm-connection-editor (ipv4)
ipv4.ignore-auto-routes <------------- in nm-connection-editor (ipv4 routes)
ipv4.ignore-auto-dns
ipv4.never-default
ipv6.may-fail<----------------------- in nm-connection-editor (ipv6)
ipv6.ignore-auto-routes <------------- in nm-connection-editor (ipv6 routes)
ipv6.ignore-auto-dns
ipv6.never-default

ipv4.dhcp-client-id
ipv4.dhcp-timeout
ipv4.dhcp-send-hostname
ipv4.dhcp-hostname
ipv4.dhcp-fqdn
ipv6.dhcp-send-hostname
ipv6.dhcp-hostname

Originally reported by @hartsjc in #17 (comment)
The network_connections struct is a good general data model for network connections, and could be used by more than just the linux-system-roles.network role. The value of this struct would be greatly increased if other attributes could be added, beyond what is useful by this role. However, adding user-defined attributes to network_connections that are not recognized by this role generates a failure.
Please consider tolerating user-defined attributes within the network_connections struct, without generating a failure in the linux-system-roles.network role
Example below. Note addition of non-standard "libvirt_dev", for use by another role in the same playbook. I use this to create a VM by generating a domain.xml with matching network devices which I supply to the libvirt module. Then when the VM is running, I could apply the linux-system-roles.network role to the guest. However, this does not work, because linux-system-roles.network generates a failure because of my addition "libvirt_dev" attribute.
network_connections:
If it is necessary to maintain a level of restrictiveness to the schema, I'd request either creating a new "network_user_attrs" data element which contains a list of user-defined attributes to be allowed within the struct, or use of a prefix such as "user_" for user-defined attributes.
on RHEL 6, when removing a bond using state=absent, it removes the config files but does not actually down the bond interface.
Subsequent attempts to down the bond via playbook fails as it states that there is no connection defined.
Needs the ability to modify a physical or virtual interface, regardless of a configuration or "connect profile" existing.

When installing rhel on a new virtual machine with 6 network interfaces, all interfaces are auto configured and activated with profile names that may or may not match the linux device name.

No matter if I use mac
or interface_name
, I get the following errors:

Instead of defaulting to a network provider depending on the platform check if the network service or NetworkManager are already enabled and use the respective service.
When the role runs and configures the network, it determines success based on whether it was able to perform all requested configurations.
But it would be useful, to extend this and determine success based on certain properties by proping the network. For example, is a certain LLDP neighbour visible? Did we get a certain address from DHCP? Is a certain host reachable via ping/arping?
In conjunction with #33, such an extended connectivity check is useful to determine success/failure, and whether to restore the previous configuration (rollback).
Maybe these checks should be implemented as a separate module, not inside network_connections.py
.
I need to create macvlan interfaces and patched the module to support these interfaces. It's just 20 lines and it works for me (tm). You can find it here: macvlan.diff.txt. I've so far used it on a Centos 7 with NetworkManager.
A problem with the initscripts provider could be that by default, there don't seem to be if{down,up}-macvlan scripts. A version of these can be found here: https://github.com/larsks/initscripts-macvlan
I haven't tested these, but they look simple enough.
Another approach would be to simply not support macvlan connections on initscripts systems.
I'll be happy to adapt my patch if needed.
Best,
Roland
There seem to be support for MTU in the code (but see #19), but I can't find it in the README.
The initscripts backend requires brctl for bridge support, however brctl might be missing on for example on CentOS6 images:

I guess we have these options:
There is a commit in a fork that indicates there is a problem with package installation

This needs investigation.
Ansible 2.7 does not allow to specify variables when including tasks anymore, this breaks this syntax:
- name: Remove interfaces
hosts: all
tasks:
- include_tasks: tasks/manage-test-interface.yml state=absent
Possible alternative is:
- name: Remove interfaces
hosts: all
tasks:
- include_tasks: tasks/manage-test-interface.yml
vars:
state: absent
Tools like virt-builder and virt-customize run commands within libguestfs managed qemu images to configure linux systems. I thought it might be possible to use the network system role to configure networking within a VM image prior to booting, however the role seems to want to enable NetworkManager, which is something we don't want to do at image configure time. It would be great if the network role would configure the networking scripts in an offline VM image.
For what it's worth, I'm running...
LIBGUESTFS_BACKEND=direct virt-customize -a testvm.qcow2 --copy-in `pwd`/pb.yml:/root --run-command 'ansible-playbook /root/pb.yml'

Ideally there would be an independent check for the network_connections
to create a clear error message. Maybe just referencing network_connections
early helps.
Currently, the module collects all logging statements, and at the end returns them as "warnings", so that they are shown by ansible. Obviously, these are not really warnings, but rather debug information.
Instead, the logging messages should be returned in a different json field that is ignored by ansible. Then, the tasks/main.yml
should have a follow-up debug
task that prints the returned variable.
I guess, in the failure case, the network_connections
task must run ignoring failures to reach the debug
statement. Then, a follow up task should check whether the network_connections
task failed and abort.
Need the ability to execute operations based only on hardware address or naming (mac, pci address, kernel device name) as opposed to only by "connection profile" name, which is very weak when using initscript style naming.
For example, in my hardware inventory, I know all of my MAC addrs, but possibly due to inconsistent net device naming or other reasons, the connection names are inconsistent.
Need the ability to [down/up, delete/rename conn name, modify attributes] of any NICs based on MAC or pci addr
The states present
and absent
are supposed to only deply/remove the persistant networking profiles on the host. They are not supposed to actually change the networking in any way. That is what the states up
and down
are for.
For initscripts, this is rather trivially the case, because the present
/absent
states just ensure that the ifcfg files are there or absent.
For NetworkManager, it's more complicated.
deleting a profile that is currently active causes the device to go down. That is, because in NetworkManager an active device must always have a profile. The solution in 1.10 is Update2()
with the NM_SETTINGS_UPDATE2_FLAG_VOLATILE
flag. Volatile means, that the connection is in-memory only, and will be automatically deleted once it goes down. If you make a connection volatile that currently is not active, it will be deleted right away.
adding or modifying a profile might always make it a candidate for autoconnecting. For state present, we would like to add/modify the profile without any changes. For that, 1.10 supports Update2()
flag NM_SETTINGS_UPDATE2_FLAG_BLOCK_AUTOCONNECT
. That works for the update case, but doesn't work for the add case. To add a connection that has connection.autoconnect=yes
without activating it right away, we would either need new NetworkManager D-Bus API to block autoconnect form the start, or we first add the connection with connection.autoconnect=no
, and then follow up with an Update2
call that sets connection.autoconnect=yes
and uses NM_SETTINGS_UPDATE2_FLAG_BLOCK_AUTOCONNECT
.
modifying the properties connection.metered
or connection.zone
takes effect immediately. There is currently no way to prevent that. NetworkManager should get a new flag for Update2
that allows to modify the profile and prevent these two properties from updating right away. Then, the role should use this new API.

How can I solve this?
Thanks.
Currently the role fails when ask to set a profile to down
when the profile is not completely defined in the profile and does not exist on the target system. One could argue that a profile is down
when it does not exist on the system. However, one could also argue that the role should report this as an error in case there is a typo. Introduce a setting called ignore-error-if-absent
that when it is true ignores the error when a profile is undefined and should be set to down
.
Hello,

network-scripts in F29 and newer uses iproute to setup bridges instead of brctl, therefore brctl does not need to be installed there anymore to support bridges.
Currently initscripts is only tested on RHEL 6 systems.

NetworkManager's Checkpoint feature allows to record the current configuration (snapshot), together with a timeout. Commonly, the user/script then would go ahead and change the networking configuration. If the timeout expires without the checkpoint being expired, the configuration of the snapshot is restored. The user can also manually issue a rollback before the timeout expires, or just cancel the timeout (in which case the snapshot is forgotten).
This can be used for two cases:
name
used to specify only the profile name and interface_name
or mac
could be specified to define the interface that the profile is restricted, too. This seems to be unexpected, since a profile called eth0
might configure eth2
if no interface_name
or mac
is specified. Therefore change it to
name
is used as interface_name
interface_name
is explicitly set empty, it will not be setmac
is specified, interface_name
defaults to not being setWhen a connection is to be removed connection['type']
causes a KeyError when using the initscripts backend and no type is defined. This should fix it:

Hoping that I did not misunderstand a fundamental aspect of how this role works, I encountered the following issue:

Incidentally the specified IPs match the current system configuration, so no actual changes should be taking place anyway but it still fails. If you need any other info or logs from the system, please let me know.
