Getting started with Longhorn

Add S3 backup to Truenas Scale using Minio

How to create certificate to use https Setup Minio on Truenas Scale

• choose certificate to use
• create new dataset for Minio to use
• In Minio create new bucket and access keys

Note: "backupTarget: s3://s3-longhorn-backup@eu-north-se2/"

• s3-longhorn-backup = bucket in Minio
• eu-north-se2 = server location in Minio

# Base64 encode secret
echo -n "https://myurl.io:9002" | base64

# output from above is added to longhorn.secret.yaml

# Sops/Age encrypt secret file to proper sops yaml. 
encrypt longhorn.secret.yaml > longhorn.secret.sops.yaml

Restore backup

# List pvc and connected volume/pv
 k -n observability get pvc uptime-kuma-pvc

# Scale down deployment
 k -n observability scale deployment uptime-kuma --replicas 0

# In UI - Volume Tab
# 1. wait for volume to be detached
# 2. copy name of PV volume
# 3. delete the volume
# In UI - Backup Tab
# 4. restore latest backup - use name of old volume
# In UI - Volume
# 5. Create PV/PVC(accept all predefined settings)    

# Scale up deployment
 k -n observability scale deployment uptime-kuma --replicas 1

# Now the backup volume be attached to new pod
