- Created a new script `instalL_asciinema.sh` to automate the installation of asciinema. - The script detects the operating system and architecture to download the appropriate binary. - Supports Linux (both musl and GNU) and macOS (Darwin). - Sets executable permissions for the downloaded binary and verifies the installation by displaying the version.

# MVK for pre-production
|
|
|
|
The **V** in MVK is for *viable*, so why is MVK viable for 3 or more nodes ?

why is MVK 'viable' ?
|
|
|
|
Out of the box K8s examples and some deployments are not useable without other externalities
|
|
|
|
* Persistent storage - often built in to managed kubernetes cloud platforms
|
|
* Ingress - is also provided by cloud providers, K8s does not natively have this
|
|
* ETCD is often offered as the 'management plane', again as part of managed kubernetes by cloud providers
|
|
|
|
K3s does not use k8s traditional 3 node ETCD unless you configure it to do so
|
|
|
|
MKK's infctl pipelines configure 3 node k3s on all 3 nodes
|
|
|
|
it also adds Longhorn for persistent storage
|
|
|
|
ingress is impossible without metallb and some kind of load balancer - traefik being my preference but others could be used, of course
