The exo compute block-storage command is a key component of the Exoscale CLI, enabling users to manage persistent block storage volumes for compute instances in the Exoscale cloud.

Block storage provides high-performance, scalable disks that persist independently of instance lifecycles, perfect for databases, logs, or any data requiring durability and low-latency access. Operations include creating volumes with custom sizes (1-16,000 GB), attaching/detaching to instances by service name or ID, listing with filters by zone/instance/size, resizing online/offline, snapshotting for backups/clones, retrieving details, and deletion.

Supports zone-specific targeting (e.g., de-1, ch-dk-2), multiple output formats for automation (JSON/YAML/table), and integrates with Exoscale IAM for secure access. Requires API key setup via exo account login.

Volumes support encryption and are billed per GB-month. Snapshots are incremental and zone-transferable. Ideal for DevOps workflows, CI/CD, and production storage orchestration.

Always detach volumes before instance termination to avoid data loss.

Volumes must be detached from instances before resizing or deleting. API rate limits apply. Encrypted volumes require key management.

Part of Exoscale CLI (exo) released in 2018 (v0.1.0). Block storage commands added early 2019 with API v2; evolved with features like snapshots (2020) and online resize (2022). Tracks Exoscale Compute API updates.
