Usage

This tool can be used to create a new class 'environment' generated from custom inventory.

See all the nodes available from reclass inventory (including generated nodes):

reclass-tools list-nodes

See only VCP nodes for specific domain:

reclass-tools list-nodes -d mcp11-ovs-dpdk.local --vcp-only

See only non-VCP nodes for specific domain (baremetal nodes):

reclass-tools list-nodes -d mcp11-ovs-dpdk.local --non-vcp-only

Find specific key in the path (without reclass render):

reclass-tools get-key parameters._param.cluster_domain /srv/salt/reclass/classes/cluster/physical_mcp11_ovs_dpdk/

Collect all parameters._param into a single dict, to track _param changes from commit to commit:

reclass-tools list-params /srv/salt/reclass/classes/

Trace all the modifications of the pillar key _param:keepalived_vip_interface during loading the model:

reclass-tools trace-key _param:keepalived_vip_interface --node=ctl01.virtual-mcp-ocata-cicd.local

Requirements

• Installed and configured 'reclass' package
• Prepared 'cluster', 'system' and 'service' classes
• [Optional] Nodes generated with salt-call state.sls reclass.storage

Create 'environment' class

This is a PoC of creating the 'environment' class. For CI tests, please generate your 'inventory.yaml' for step #3 and create the cookiecutter template based on example template from /examples directory.

For this example will be used the 'cluster' model 'mcp11-ovs-dpdk.local' from 'mcp-baremetal-lab' repo.

All steps should be performed on the installed salt-master node, when all nodes have been generated with 'reclass.storage' state.

1. Create a context file with nodes list and 'linux.network.interface' configuration from the current reclass inventory.

reclass-tools show-context -d mcp11-ovs-dpdk.local parameters.linux.network.interface > /tmp/context-mcp11-ovs-dpdk.local.yaml

2. Remove existing hardware-related 'linux.network.interface' object from 'cluster', 'system' and 'service' classes. WARNING! Make sure that you have created the context file with 'linux.network.interface' as a backup.

reclass-tools del-key parameters.linux.network.interface /srv/salt/reclass/classes/cluster/physical_mcp11_ovs_dpdk
reclass-tools del-key parameters.linux.network.interface /srv/salt/reclass/classes/system/
reclass-tools del-key parameters.linux.network.interface /usr/share/salt-formulas/reclass/

3. Render the 'environment' class using example template based on cookiecutter:

git clone https://github.com/dis-xcom/reclass_tools ~/reclass_tools
reclass-tools render -e lab03_ovs_dpdk -t ~/reclass_tools/examples/environment -o /tmp/environment -c /tmp/context-mcp11-ovs-dpdk.local.yaml  # You can add multiple YAMLs here

4. Check that the 'environment' has been created

tree /tmp/environment/

5. Symlink 'environment' to the /srv/salt/reclass/classes

ln -s /tmp/environment /srv/reclass/salt/classes

6. Add new class '- environment.mcp11-ovs-dpdk.local' to the classes/cluster/<cluster_model>/infra/config.yml (edit the file manually for now)

7. Update the nodes for reclass inventory

salt-call state.sls reclass.storage
