| Method | Pros (current state) | Cons (current state) | Prerequisites |
|---|
| Manual installation | - Full control over each step
- Easy to understand and replicate
- Already available (see next chapter on this page)
| - Requires user intervention
- Requires certain prerequisites be met on cluster nodes apriori
| - preinstalled operating system (Ubuntu 16.04/18.04) on all involved nodes
|
| Script-based installation | - High degree of flexibility via arguments
- Portable
- Can be used in CI/CD, assuming baremetal nodes are pre-provisioned, e.g. for shorter test cycles like a patch verify job where we'd want to avoid reinstalling the operating system each time
| - Implementation currently in progress
- Fixed number of nodes (1 master + 1 worker)
- Requires certain prerequisites be met on cluster nodes apriori
| - preinstalled operating system (Ubuntu 16.04/18.04) on all involved nodes
- user with passwordless sudo access already available on the target nodes
|
| OPNFV-based installer(s) | - Unified and standardized input configuration files (PDF/IDF)
- Can be used in CI/CD
- Can handle OS provisioning on its own, for virtual, baremetal or hybrid PODs
| - Not yet implemented
- Requires hardware descriptor files (PDF/IDF)
| - Jumpserver (installer) node preinstalled
- XDF (PDF/IDF) available for the target lab
|
| Heat stack | | - Not implementedtested on aarch64 yet
- Uses VMs rather than baremetal
| - Openstack cloud preinstalled
|
| Other installer solutions (e.g. Airship) | - Alignment with industry standard installer solutions for K8s
| - Not implemented
- More complex design and configuration
- Might be overkill for IEC, at least with the current requirements

Firstly, we should get the configuration file from web site and modify the corresponding image from amd64 to arm64 version. Then, by using kubectl, the calico pod will be created.

Since the "quay.io/calico" image repo does not support does not multi-arch, we have to replace the “quay.io/calico” image path to "calico" which supports multi-arch.

Heat Orchestration Templates
Prerequisites:
- Openstack Ocata or latest
Recommended configuration:
- 2 or more compute nodes with enough RAM and disk (128 GB of RAM, 2 TB disk space)
- DPDK is optional but it is recommended
The scripts and templates can be found in the Akraino iec git repository:
