How to create a new daily chain...

1) Declare the chain in chained-ci inventory

...

All the chains must be declared in https://gitlab.com/Orange-OpenSource/lfn/ci_cd/chained-ci/-/blob/master/pod_inventory/inventory

onap_oom_staging_k8s_azure_1
onap_oom_gating_azure_3
onap_oom_gating_azure_4
onap_oom_staging_azure_1

In the example above I declared 2 new chains: new_k8s_daily and new_onap_daily.

Note that you can declare only one but for the daily we are used to redeploy the k8s prior to the ONAP deployment - we always restart from scratch. it allows to see any regression on OOM/k8s.

2) Create the chains

Once declare you must create several files

Let's start with the host vars https://gitlab.com/Orange-OpenSource/lfn/ci_cd/chained-ci/-/tree/master/pod_inventory/host_vars.

You must create the files: new_k8s_daily.yml and new_onap_daily.yml

These files describe the chain you want to setup

Let's consider new_k8s_daily.yml, it could look like

There are lots of information in this file, it describes the different stages of the kubernetes installation: config (init), infra_deploy (creation of the VMs on Orange OpenStack), k8s_deploy (deployement of the kubernetes), k8s_test (kubernetes testing).

For each stage we may change some parameters..

on the config part: the full configration of the VM is indicated through the parameter infra: k8s18-new-daily (see next section)
on the VM creation for instance we can change the name of the tenants/vms/users/...
on the kubernetes installation we can change the versions of kubespray, helm, the network plugin,the kubernetes release...This section must be in line with the OOM recommendations
We also do precise the docker repository (here we use our internal mirror)

Same for the ONAP installation (chained once the kubernetes is installed)

      TEST_RESULT_DB_URL: http://testresults.opnfv.org/onap/api/v1/results

We find back the notion of stages: config (retrieve information from VMs and k8s installation), vnf_project_deploy (create a tenant for the test), onap_deploy (ONAP deployment), onap_test (tests to be executed on ONAP linked to the gitlab project onap_test)

Here again you can modify some parameters. in the onap_deploy stage you can specify the branch of the oom_installer (here master) and the branch of OOM

3) Resources definition

In the k8s chain definition, a parameter infra was set to precise the resources. These resources are defined in the associated pdf and idf files that can be found in https://gitlab.com/Orange-OpenSource/lfn/ci_cd/chained-ci/-/tree/master/pod_config/config

If we consider for instances k8s-onap-master, the 2 files are:

Infrastructure Description File (IDF): https://gitlab.com/Orange-OpenSource/lfn/ci_cd/chained-ci/-/blob/master/pod_config/config/idf-k8s18-onap-master.yaml
Platform Description File (PDF): https://gitlab.com/Orange-OpenSource/lfn/ci_cd/chained-ci/-/blob/master/pod_config/config/k8s18-onap-master.yaml

the parameters defined here are used by the collection infra managers to create the VM and or deploying infrastructure and platform components.

4) Summary

If you want to create a new daily

clone chained-ci repo
git clone https://gitlab.com/Orange-OpenSource/lfn/ci_cd/chained-ci.git
add onap-daily-k8s-x and onap-daily-x in the inventory https://gitlab.com/Orange-OpenSource/lfn/ci_cd/chained-ci/-/blob/master/pod_inventory/inventory
copy/paste master host_vars
- cd chained-ci/pod_inventory/host_vars
- cp onap_daily_pod4_k8s_master.yml onap_daily_x_k8s.yml
- cp onap_daily_pod4_master.yml onap_daily_x.yml
- Edit and adapt the chains
  - e.g. change the OOM branch to x in onap_daily_x.yml, update the versions of kubernetes, helm,..according to OOM recommentations
  - if resources changes, create an idf and pdf file in chained-ci/pod_config/config/ (note if resources are unchanged you may just reuse existing ones or copy paste existing ones for clarity)
    - cp chained-ci/pod_config/config/idf-k8s18-onap-master.yaml chained-ci/pod_config/config/idf-k8s18-onap-x.yaml
    - cp chained-ci/pod_config/config/k8s18-onap-master.yaml chained-ci/pod_config/config/k8s18-onap-x.yaml
    - and then reference infra: k8s18-onap-x in onap_daily_x_k8s.yml
add a schedule in gitlab vi with TARGET=onap-daily-x
