Huawei Cloud CCI Container Instance Lifecycle Management

Overview

Manage Huawei Cloud CCI (Cloud Container Instance) full lifecycle using hcloud CLI (KooCLI). CCI is a serverless container service — no cluster management needed, just create a Namespace, define a Network, then deploy workloads directly.

Architecture: hcloud CLI → CCI OpenAPI → Namespace / Network / Deployment / StatefulSet / Pod / EIPPool / Service / Ingress

Constraints and Rules

Security Rules

Two-step confirmation: All destructive operations (delete Namespace/Network/Deployment/StatefulSet/Pod/EIPPool) require explicit user confirmation — preview command, resource details, and risk warning first; execute only after user confirms.
Credential security: Never expose AK/SK values in conversation, commands, or output. Only use hcloud configure list to check credential status (presence only). Prefer profile mode or environment variables over explicit AK/SK parameters.

Resource Constraints

Namespace flavor annotation is mandatory: Every namespace must carry namespace-kubernetes-io/flavor annotation (value: general-computing or gpu-accelerated). Without it, creation fails.
limits must equal requests: CCI enforces resources.limits == resources.requests. Mismatch causes "limit and request doesn't equal" error. Set both to the same values (e.g., 500m/1Gi).
Network must precede workloads: Pod/Deployment/StatefulSet creation fails or stays Pending if no Network exists in the namespace. Always create Network before deploying workloads.
VPC CIDR restriction: VPC subnet CIDR must NOT be 10.247.0.0/16 — CCI reserves this range for Service networking. Using it causes IP conflicts and workload creation failures.
Deletion order: Pod → Deployment/StatefulSet → EIPPool → Network → Namespace. Deleting a Namespace cascades all resources under it.

hcloud CLI Constraints

Network creation must use Python helper script: hcloud CLI cannot pass annotation keys containing dots (network.alpha.kubernetes.io/default-security-group). Neither dot notation nor --cli-jsonInput works. Use scripts/cci_network_helper.py.
Namespace annotation uses hyphen replacement: Keys like namespace.kubernetes.io/flavor can use hyphens (namespace-kubernetes-io/flavor) and CCI auto-normalizes. This workaround only works for Namespace, NOT for Network.
Always verify parameters with --help: CCI has hundreds of parameters. Run hcloud CCI <Operation> --help before constructing any command. The help output is the authoritative source.

Detailed breakdowns of these rules are in Security Constraints, hcloud CLI Limitations, and Precautions.

Standard Workflow

1. Create Namespace (with flavor annotation)
2. Create Network (requires Python helper script for annotation — see hcloud CLI Limitations)
3. Create Deployment / StatefulSet / Pod (run workloads)
4. Query status, view logs
5. (Optional) Create EIPPool for Pod public IP access
6. Cleanup: delete workload → delete Network → delete Namespace

Prerequisites

Prerequisite check: hcloud (KooCLI) >= 7.2.2 required Run hcloud version to verify version >= 7.2.2, and hcloud configure list to check profile exists. If not installed or version is too low, refer to the huawei-cloud-cli-guidance skill for installation guide.

Security Constraints

Dangerous Operation Confirmation Mechanism

This skill strictly enforces a two-step confirmation mechanism for all destructive operations.

All destructive operations require explicit user confirmation before execution. The process:

Step 1: Preview — Show the command, resource details, and risk warning

Step 2: Confirm & Execute — Only after user explicitly confirms

Operations Requiring Confirmation

Operation	Risk Level	Description
Delete Namespace	🔴 Critical	Cascades — deletes ALL resources under this namespace (Network, Pods, Deployments, etc.)
Delete Network	🟠 High	Disconnects namespace from VPC; running pods lose network
Delete Deployment	🟠 High	Terminates all replicas of the workload
Delete StatefulSet	🟠 High	Terminates all replicas; PVC data may be lost
Delete Pod	🟠 High	Terminates the container instance
Delete EIPPool	🟡 Medium	Releases public IPs allocated to pods

Credential Security

Never expose AK/SK values in conversation, commands, or output
Never ask user to input AK/SK directly in conversation
Only use hcloud configure list to check credential status (presence only, not values)
Prefer profile mode or environment variables over explicit AK/SK parameters

Command Format Standard

CCI follows the standard hcloud format with Kubernetes-style nested parameters:

hcloud CCI <Operation> --param=value --cli-region=<region> --cli-output=json

CCI-Specific Parameter Rules

CCI parameters follow Kubernetes API conventions — deeply nested objects with dot notation:

Annotations use {*} format: --metadata.annotations.namespace-kubernetes-io/flavor=general-computing
Labels use {*} format: --metadata.labels.app=my-app
Containers array (1-based): --spec.template.spec.containers.1.name=main --spec.template.spec.containers.1.image=nginx
Resources use {*} format: --spec.template.spec.containers.1.resources.limits.cpu=500m
Selector matchLabels use {*} format: --spec.selector.matchLabels.app=my-app
Namespaced operations require --namespace: all workload operations must specify namespace

⚠️ Critical: Before constructing any CCI command, always run hcloud CCI <Operation> --help to verify exact parameter names. CCI has hundreds of parameters; the help output is the authoritative source.

Parameter Format Details

Core Commands

Namespace

# Create namespace (general-computing flavor)
hcloud CCI createCoreV1Namespace \
  --metadata.name=<ns-name> \
  --metadata.annotations.namespace-kubernetes-io/flavor=general-computing \
  --cli-region=<region \
  --cli-output=json

# List namespaces
hcloud CCI listCoreV1Namespace --cli-region=<region> --cli-output=json

# Read namespace details
hcloud CCI readCoreV1Namespace --name=<ns-name> --cli-region=<region> --cli-output=json

# Delete namespace (TWO-STEP CONFIRMATION REQUIRED)
hcloud CCI deleteCoreV1Namespace --name=<ns-name> --cli-region=<region>

Network

⚠️ hcloud CLI limitation: Network creation requires a Python helper script because hcloud CLI cannot pass the annotation key network.alpha.kubernetes.io/default-security-group (contains dots that hcloud treats as nested levels). The --cli-jsonInput approach also doesn't work due to an hcloud bug where annotations show in --dryrun but aren't transmitted in actual requests. See hcloud CLI Limitations below.

# Step 1: Get VPC subnet details (including neutron_network_id)
hcloud VPC ShowSubnet --vpc_id=<vpc-id> --subnet_id=<subnet-id> --cli-region=<region> --cli-output=json

# Step 2: Create network via Python helper script
python scripts/cci_network_helper.py create \
  --namespace=<ns-name> \
  --name=<network-name> \
  --vpc-id=<vpc-id> \
  --subnet-id=<subnet-id> \
  --network-id=<neutron-network-id> \
  --security-group-id=<sg-id> \
  --region=<region>

# Step 3: Check network status until Active
hcloud CCI readNetworkingCciIoV1beta1NamespacedNetworkStatus \
  --name=<network-name> \
  --namespace=<ns-name> \
  --cli-region=<region> \
  --cli-output=json

# List networks
hcloud CCI listNetworkingCciIoV1beta1NamespacedNetwork \
  --namespace=<ns-name> \
  --cli-region=<region> \
  --cli-output=json

Required Network spec fields: Network creation requires attachedVPC, subnetID, networkType, AND networkID (neutron network ID). The networkID field is REQUIRED — it is the neutron network ID obtained from hcloud VPC ShowSubnet.

Required Network annotation: network.alpha.kubernetes.io/default-security-group (the correct annotation key for CCI Network security group, NOT security-group-id). This annotation must be set to the security group ID.

Deployment

# Create deployment
hcloud CCI createAppsV1NamespacedDeployment \
  --namespace=<ns-name> \
  --metadata.name=<deploy-name> \
  --spec.replicas=1 \
  --spec.selector.matchLabels.app=<deploy-name> \
  --spec.template.metadata.labels.app=<deploy-name> \

  --spec.template.spec.containers.1.resources.requests.cpu=500m \
  --spec.template.spec.containers.1.resources.requests.memory=1Gi \
  --cli-region=<region> \
  --cli-output=json

# Scale deployment
hcloud CCI patchAppsV1NamespacedDeploymentScale \
  --name=<deploy-name> \
  --namespace=<ns-name> \
  --spec.replicas=<new-replicas> \
  --cli-region=<region>

# Read deployment status
hcloud CCI readAppsV1NamespacedDeploymentStatus \
  --name=<deploy-name> \
  --namespace=<ns-name> \
  --cli-region=<region> \
  --cli-output=json

StatefulSet

# Create statefulset
hcloud CCI createAppsV1NamespacedStatefulSet \
  --namespace=<ns-name> \
  --metadata.name=<sts-name> \
  --spec.replicas=1 \
  --spec.selector.matchLabels.app=<sts-name> \
  --spec.template.metadata.labels.app=<sts-name> \
  --spec.template.spec.containers.1.name=<container-name> \
  --spec.template.spec.containers.1.image=<image> \
  --spec.template.spec.containers.1.resources.limits.cpu=500m \
  --spec.template.spec.containers.1.resources.limits.memory=1Gi \
  --cli-region=<region> \
  --cli-output=json

# Read statefulset status
hcloud CCI readAppsV1NamespacedStatefulSetStatus \
  --name=<sts-name> \
  --namespace=<ns-name> \
  --cli-region=<region> \
  --cli-output=json

Pod

# Create pod (single container instance)
hcloud CCI createCoreV1NamespacedPod \
  --namespace=<ns-name> \
  --metadata.name=<pod-name> \
  --spec.containers.1.name=<container-name> \
  --spec.containers.1.image=<image> \
  --spec.containers.1.resources.limits.cpu=500m \
  --spec.containers.1.resources.limits.memory=1Gi \
  --cli-region=<region> \
  --cli-output=json

# Read pod status
hcloud CCI readCoreV1NamespacedPodStatus \
  --name=<pod-name> \
  --namespace=<ns-name> \
  --cli-region=<region> \
  --cli-output=json

# Read pod logs
hcloud CCI readCoreV1NamespacedPodLog \
  --name=<pod-name> \
  --namespace=<ns-name> \
  --container=<container-name> \
  --cli-region=<region>

EIPPool

# Create EIPPool (for pod public IP access — auto-create EIPs)
hcloud CCI createCrdYangtseCniV1NamespacedEIPPool \
  --namespace=<ns-name> \
  --apiVersion=crd.yangtse.cni/v1 \
  --kind=EIPPool \
  --metadata.name=<eippool-name> \
  --spec.amount=1 \
  --spec.eipAttributes.networkType=5_bgp \
  --spec.eipAttributes.ipVersion=4 \
  --spec.eipAttributes.bandwidth.shareType=PER \
  --spec.eipAttributes.bandwidth.size=5 \
  --spec.eipAttributes.bandwidth.chargeMode=bandwidth \
  --spec.eipAttributes.bandwidth.name=<bw-name> \
  --cli-region=<region> \
  --cli-output=json

# Read EIPPool status
hcloud CCI readCrdYangtseCniV1NamespacedEIPPoolStatus \
  --name=<eippool-name> \
  --namespace=<ns-name> \
  --cli-region=<region> \
  --cli-output=json

EIPPool required fields: --apiVersion=crd.yangtse.cni/v1 and --kind=EIPPool are mandatory. spec.eipAttributes.networkType is required (values: 5_bgp for dynamic BGP, 5_gray for dedicated load balancing). spec.eipAttributes.bandwidth.chargeMode and name are required when auto-creating EIPs.

Pod EIP binding: To assign an EIPPool to a Pod, add annotation yangtse.io/eippool=<eippool-name> (use hyphen workaround: --metadata.annotations.yangtse-io/eippool=<eippool-name>).

VPC/Subnet Prerequisites

CCI workloads run inside a Network that maps to an existing VPC subnet. Before creating a Network, query available VPCs and subnets, and obtain the neutron network ID (required for Network creation):

# List VPCs
hcloud VPC ListVpcs --cli-region=<region> --cli-output=json

# List subnets
hcloud VPC ListSubnets --cli-region=<region> --cli-output=json

# Get subnet details (including neutron_network_id — REQUIRED for Network creation)
hcloud VPC ShowSubnet --vpc_id=<vpc-id> --subnet_id=<subnet-id> --cli-region=<region> --cli-output=json

⚠️ VPC subnet CIDR restriction: The VPC and subnet CIDR must NOT be 10.247.0.0/16 — this range is reserved by CCI for Service networking. Using it causes IP conflicts and workload creation failures.

⚠️ neutron_network_id is required: The neutron_network_id from VPC ShowSubnet output is the value for the networkID field in Network spec. This field is REQUIRED for Network creation.

Namespace Flavor Types

Flavor Value	Description	Use Case
`general-computing`	General computing type	Standard workloads, web services, microservices
`gpu-accelerated`	GPU accelerated type	AI, ML, high-performance computing

This annotation is mandatory when creating a namespace. Without it, namespace creation will fail.

Resource Quota and Limits

CCI enforces resource quotas per namespace. Common defaults:

Resource	Default Limit
Pods	varies by region
CPU per Pod	0.25 - 8 cores
Memory per Pod	0.5Gi - 32Gi
PVCs	varies

Query current quotas:

hcloud CCI listCoreV1NamespacedResourceQuota \
  --namespace=<ns-name> \
  --cli-region=<region> \
  --cli-output=json

Output Format

JSON (recommended)

hcloud CCI <Operation> --cli-region=<region> --cli-output=json

Table (for manual viewing)

hcloud CCI <Operation> --cli-region=<region> --cli-output=table

JMESPath Filtering

# Filter deployment replicas and status
hcloud CCI readAppsV1NamespacedDeploymentStatus \
  --name=<deploy-name> --namespace=<ns-name> \
  --cli-region=<region> --cli-output=json \
  --cli-query="{replicas:status.replicas,ready:status.readyReplicas,available:status.availableReplicas}"

# Filter pod phase
hcloud CCI readCoreV1NamespacedPodStatus \
  --name=<pod-name> --namespace=<ns-name> \
  --cli-region=<region> --cli-output=json \
  --cli-query="status.phase"

Debugging

Add --cli-debug=true to any command for detailed request/response information:

hcloud CCI <Operation> --cli-debug=true --cli-region=<region>

Parameter Confirmation

Before executing any CCI operation, confirm the following parameters:

Parameter	Required	Description	Source
`--namespace`	Yes	CCI namespace name	Existing or newly created
`--cli-region`	Yes	Huawei Cloud region ID	`HUAWEI_CLOUD_REGION` or config
`--metadata.name`	Yes	Resource name (Pod/Deployment/Network etc.)	User specified
`--metadata.annotations.namespace-kubernetes-io/flavor`	Yes (Namespace)	Flavor type: `general-computing` or `gpu-accelerated`	User choice
VPC/Subnet ID	Yes (Network)	From `VPC ListVpcs` / `VPC ShowSubnet`	Query existing resources
neutron_network_id	Yes (Network)	From `VPC ShowSubnet` response `neutron_network_id` field	Query result

⚠️ Recommended: run hcloud CCI <Operation> --help before any CCI command to verify parameter names, then cross-reference the table above to confirm parameter value sources.

Precautions

See references/troubleshooting.md for detailed troubleshooting.

Quick reference:

Issue	Cause	Quick Fix
Namespace creation fails	Missing flavor annotation	Add `--metadata.annotations.namespace-kubernetes-io/flavor=general-computing`
Network creation fails	Missing VPC/subnet, CIDR conflict, or missing annotation/networkID	Verify subnet ID, neutron network ID, security group ID; ensure CIDR != `10.247.0.0/16`; use Python helper script
Pod stays Pending	No Network in namespace	Create Network first
403 permission error	Insufficient IAM	Check references/iam-policies.md
Deep nested param errors	Wrong dot notation	Use `--help` to verify exact parameter path
Annotation with dots not passed	hcloud CLI treats dots as nested levels	Use Python helper script for Network creation
EIPPool creation fails (400/422)	Missing `--apiVersion=crd.yangtse.cni/v1` or `--kind=EIPPool` or `networkType`	Add all required fields (see EIPPool section)
Deployment "limit and request doesn't equal" error	CCI requires limits == requests	Set requests to same values as limits (e.g., both `500m/1Gi`)

Verification Method

See references/verification-method.md for complete verification steps.

Quick verification checklist:

Step	Command	Expected Result
Namespace creation	`hcloud CCI readCoreV1Namespace --name=<ns> --cli-region=<region>`	status.phase=Active
Network creation	`hcloud CCI readNetworkingCciIoV1beta1NamespacedNetworkStatus --name=<net> --namespace=<ns>`	status.phase=Active
Deployment creation	`hcloud CCI readAppsV1NamespacedDeploymentStatus --name=<deploy> --namespace=<ns>`	readyReplicas >= 1
Pod creation	`hcloud CCI readCoreV1NamespacedPodStatus --name=<pod> --namespace=<ns>`	status.phase=Running

Best Practices

Namespace isolation: Use different namespaces for different teams/projects to avoid resource conflicts
EIPPool on-demand: Only create EIPPool when Pod public IP access is needed

hcloud CLI Limitations

⚠️ Critical: hcloud CLI has known limitations that affect CCI operations. Understanding these is essential for successful Network creation.

Limitation	Impact	Workaround
Cannot pass annotation keys containing dots (.) via CLI parameters	hcloud treats dots in parameter names as nested object levels, so `--metadata.annotations.network.alpha.kubernetes.io/default-security-group` creates a deeply nested structure instead of a single annotation key	Use Python helper script (`scripts/cci_network_helper.py`) for Network creation
`--cli-jsonInput` doesn't properly transmit annotations	hcloud bug: annotations appear in `--dryrun` output but are not transmitted in actual API requests	Use Python helper script instead
`--cli-jsonInput` requires ASCII encoding	UTF-8 BOM causes JSON parsing failure	Ensure JSON input files are saved as plain ASCII (no BOM)
Namespace annotation works with hyphen replacement	Keys like `namespace.kubernetes.io/flavor` can use hyphens (`namespace-kubernetes-io/flavor`) and CCI auto-normalizes them back	This workaround only works for Namespace, NOT for Network

Why Network needs a Python helper: The Network annotation key network.alpha.kubernetes.io/default-security-group cannot be passed via hcloud CLI (neither dot notation nor --cli-jsonInput). Unlike Namespace annotations, CCI does NOT auto-normalize hyphen-replaced keys for Network resources. The Python helper script (scripts/cci_network_helper.py) constructs the correct API request body directly, bypassing these hcloud CLI limitations.
