环境信息

Kubernetes：v1.20.6
StorageClass：csi-udisk-rssd
Helm：v3.5.2
nginx-ingress: 0.47.0

Harbor 2.3.0 版本安装前检查工作

推荐至少预留 8vCPU 和 30GB Mem的资源
依赖 ingress
依赖 Redis 5.0 或者更高版本
依赖 PostgreSQL 12.x 或者更高版本

Harbor 2.3.0 版本安装前准备工作

1. 申请通证书,

可以使用 https://keymanager.org/ 来申请 Let’s Encrypt 提供的免费泛域名证书

2. 创建域名证书 secret

kubectl create ns harbor
kubectl create secret tls harbor-secret \
    --cert=harbor.crt \
    --key=harbor.key \
    -n harbor

3. 准备一个 Redis 实例

K8S集群内部署参考链接 Helm部署Redis

4. 准备一个 PostgreSQL 实例

K8S集群内署参考链接 Helm部署postgresql ,数据部署完毕后,需要创建好harbor组件需要的database，参考命令：

export POSTGRES_PASSWORD=$(kubectl get secret --namespace harbor harbor-db-postgresql -o jsonpath="{.data.postgresql-password}" | base64 --decode)

kubectl run harbor-db-postgresql-client --rm --tty -i --restart='Never' --namespace harbor --image uhub.service.ucloud.cn/ucloud_pts/postgresql:13.3.0-debian-10-r55 --env="PGPASSWORD=$POSTGRES_PASSWORD" --command -- psql --host harbor-db-postgresql -U postgres -d postgres -p 5432

CREATE DATABASE harbor_core;
CREATE DATABASE harbor_clair;
CREATE DATABASE harbor_notary_server;
CREATE DATABASE harbor_notary_signer;

5. 同步海外源镜像

在国内环境部署应用，经常因为获取国外源站容器镜像超时，导致部署失败，可以提前将容器镜像同步到本地镜像仓库中，以自有镜像仓库uhub.service.ucloud.cn/ucloud_pts 为例，login仓库，执行命令： docker login uhub.service.ucloud.cn/ucloud_pts
需要同步镜像列表如下：

docker.io/bitnami/chartmuseum:0.13.1-debian-10-r98
docker.io/bitnami/harbor-core:2.3.0-debian-10-r0
docker.io/bitnami/harbor-portal:2.3.0-debian-10-r0
docker.io/bitnami/harbor-registry:2.3.0-debian-10-r7
docker.io/bitnami/harbor-registryctl:2.3.0-debian-10-r7
docker.io/bitnami/harbor-jobservice:2.3.0-debian-10-r7
docker.io/bitnami/harbor-adapter-trivy:2.3.0-debian-10-r5
docker.io/bitnami/harbor-notary-server:2.3.0-debian-10-r7
docker.io/bitnami/harbor-notary-signer:2.3.0-debian-10-r7

关于docker pull tag push 操作可以参考：

6. 创建 imagePullSecrets

创建容器集群访问仓库地址 uhub.service.ucloud.cn/ucloud_pts，拉取镜像需要的 secret

kubectl create namespace harbor
kubectl create secret docker-registry registry-secret-name \
        --namespace=harbor \
        --docker-server=uhub.service.ucloud.cn/ucloud_pts \
        --docker-username='xxxxxx' \
        --docker-password='xxxxxx'

7. 添加 Helm仓库

这里选用BitNami提供的chart仓库

helm repo add bitnami https://charts.bitnami.com/bitnami
helm repo update

8. 定义gitlab 配置，完成gitlab部署

cat > harbor-config.yaml << EOF

  imageRegistry: uhub.service.ucloud.cn/ucloud_pts

    - "tls-harbor-core"
