2019-06-28[iec] Add basic CentOS support (virtual only)Alexandru Avadanii1-7/+33
- reclass: iec: CentOS compatibility changes: * drop `proto: static` in favor of letting the linux formula set the appropiate default based on target OS; * replace `proto: manual` with `proto: none` on RHEL systems; * system.file: Avoid using non-existing `shadow` group for system files; * load br_netfilter kernel module to avoid `linux.network` state failures; * disable `at`, `cron` due to incomplete defaults in salt-formula-linux (since we don't use them on iec nodes anyway); - jumpserver/VCP VMs: centos: enable predictable interface names: * CentOS cloud image defaults to old 'eth' naming scheme; * add necessary kernel boot options via linux state; * cleanup auto-generated udev rules for old eth interface names; - salt-formula-linux: network: RHEL: Set bridge for member interfaces * Find the bridge containing the interface being currently configured (if any) and pass it to the `network.managed` Salt call; - deploy.sh: Add new deploy argument `-o` for specifying the operating system to preinstall on jumpserver and/or VCP VMs; * defaults to 'ubuntu1604'; * only iec scenarios will also support 'centos' for now; - user-data: minor tweaks for CentOS compatability: * use `systemctl` instead of `service` utility; * explicitly enable `salt-minion` service, since it defaults to disabled on RHEL systems; * explicitly call `ldconfig` to work around stale cache on RHEL, preventing `salt-minion` from using OpenSSL library; - states: virtual_init: Skip non-existing sysctl options on CentOS: * CentOS currently uses a 3.x kernel which lacks certain sysctl options that were only introduced in 4.x kernels, so skip them; - state: akraino_iec: Add centos support: * move iec repo to `/var/lib/akraino/iec` on both Salt Master and cluster nodes; - scenario defaults: Add CentOS configuration: * OS-dependent configuration split; * CentOS base image, default packages etc.; - AArch64 deploy requirements: Add `xz` dependency * CentOS AArch64 cloud image is archived using xz, install xz tools for decompression; - xdf_data: Make yaml parsing OS agnostic: * rename `apt` to `repo` where appropiate; * OS-dependent configuration parsing; - lib_jump_deploy: CentOS handling changes: * skip filesystem resize of cloud image for CentOS; * add repo handling, package intallation/removal handling for CentOS; * unxz base image if necessary (CentOS AArch64 cloud image); Change-Id: Ic3538bacd53198701ff4ef77db62218eabc662e7 Signed-off-by: Alexandru Avadanii <Alexandru.Avadanii@enea.com>
2019-03-29[akraino] Add IEC K8-calico scenariosAlexandru Avadanii2-0/+123
- bump Pharos git submodule to allow PODs with fewer nodes; - add `k8-calico-iec-noha` scenario definition for Akraino IEC basic configuration; - add `k8-calico-iec-vcp-noha` scenario definition for Akraino IEC nested (virtualized control plane) configuration; - add `akraino_iec` state, which will leverage the Akraino IEC bootstrap scripts from [1]; - replace system.reboot salt call with cmd.run 'reboot' as it's more reliable; - use kernel 4.15 for AArch64 K8 IEC scenarios; NOTE: These scenarios will not be released in OPNFV since don't rely on Salt formulas but instead of Akraino IEC scripts to install K8s.
