### hivectl

Basic commands to setup a compute instance, block storage (viperblock), object storage (predastore)

`hivectl configure --endpoint-url https://localhost:8443/`

`hivectl auth --access_key X --secret_key Y --profile hivelocal --endpoint-url https://localhost:8443/`

Writes to ~/.aws/credentials

`hivectl vol add --size 128M --no-verify-ssl --endpoint-url https://localhost:8443/ --`

Authenticates using ~/.aws/credentials - Backend creates a unique volume id

Connects to S3, creates the /vol-uniquestr/, uploads `config.json`

```
{
  "VolumeName": "vol-uniquestr",
  "VolumeSize": 134217728,
  "BlockSize": 4096,
  "ObjBlockSize": 4194304,
  "SeqNum": 0,
  "ObjectNum": 0,
  "WALNum": 0,
  "BlockToObjectWALNum": 0,
  "Version": 1
}
```

`hivectl ec2 import-key-pair --key-name my-key-pair --public-key-material fileb://~/.ssh/id_rsa.pub`

This will upload the users SSH public key to their S3 bucket, /bucket/ec2/my-key-pair.pub

`hivectl ec2 run-instances --image-id ami-X --instance-type t3.micro --key-name my-key-pair`

This will clone an existing image-id (vol-ID, e.g debian snapshot), copy to the users S3 bucket, and start the new volume from the fresh copy.

Note when starting an image additional volumes are required.

Sample launch

Require to start NBD (EFI)

./server/nbdkit -p 10810 --pidfile /tmp/vb-vol-1-efi.pid ./plugins/golang/examples/ramdisk/nbdkit-goramdisk-plugin.so -v -f size=67108864 volume=vol-1-efi bucket=predastore region=ap-southeast-2 access_key="AKIAIOSFODNN7EXAMPLE" secret_key="wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY" base_dir="/tmp/vb" host="https://127.0.0.1:8443"

Require to start Debian volume

./server/nbdkit -p 10809 --pidfile /tmp/vb-vol-1-root.pid ./plugins/golang/examples/ramdisk/nbdkit-goramdisk-plugin.so -v -f size=4294967296 volume=vol-1-root bucket=predastore region=ap-southeast-2 access_key="AKIAIOSFODNN7EXAMPLE" secret_key="wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY" base_dir="/tmp/vb" host="https://127.0.0.1:8443"
