前言
系统环境：
-
kubernetes 版本：1.18.10 -
Harbor Chart 版本：1.5.2 -
Harbor 版本：2.1.2 -
Helm 版本：3.3.4 -
持久化存储驱动：Ceph RBD
1. Harbor 简介
简介
Harbor 是一个开放源代码容器镜像注册表，可通过基于角色权限的访问控制来管理镜像，还能扫描镜像中的漏洞并将映像签名为受信任。Harbor 是 CNCF 孵化项目，可提供合规性，性能和互操作性，以帮助跨 Kubernetes 和 Docker 等云原生计算平台持续，安全地管理镜像。
特性
-
管理：多租户、可扩展 -
安全：安全和漏洞分析、内容签名与验证
2. 创建自定义证书
安装 Harbor 我们会默认使用 HTTPS 协议，需要 TLS 证书，如果我们没用自己设定自定义证书文件，那么 Harbor 将自动创建证书文件，不过这个有效期只有一年时间，所以这里我们生成自签名证书，为了避免频繁修改证书，将证书有效期为 100 年，操作如下：
安装 cfssl
fssl 是 CloudFlare 开源的一款 PKI/TLS 工具,cfssl 包含一个命令行工具和一个用于签名，验证并且捆绑 TLS 证书的HTTP API服务,使用 Go 语言编写.
github: https://github.com/cloudflare/cfssl[1]
下载地址: https://pkg.cfssl.org/[2]
macOS 安装步骤：
? → brew install cfssl
通用安装方式：
? → wget https://pkg.cfssl.org/R1.2/cfssl_linux-amd64 -O /usr/local/bin/cfssl
? → wget https://pkg.cfssl.org/R1.2/cfssljson_linux-amd64 -O /usr/local/bin/cfssljson
? → wget https://pkg.cfssl.org/R1.2/cfssl-certinfo_linux-amd64 -O /usr/local/bin/cfssl-certinfo
? → chmod +x /usr/local/bin/cfssl*
获取默认配置
? → cfssl print-defaults config > ca-config.json
? → cfssl print-defaults csr > ca-csr.json
生成 CA 证书
将ca-config.json内容修改为：
{
"signing": {
"default": {
"expiry": "876000h"
},
"profiles": {
"harbor": {
"expiry": "876000h",
"usages": [
"signing",
"key encipherment",
"server auth"
]
}
}
}
}
修改ca-csr.json文件内容为：
{
"CN": "CA",
"key": {
"algo": "rsa",
"size": 2048
},
"names": [
{
"C": "CN",
"ST": "hangzhou",
"L": "hangzhou",
"O": "harbor",
"OU": "System"
}
]
}
修改好配置文件后,接下来就可以生成 CA 证书了：
? → cfssl gencert -initca ca-csr.json | cfssljson -bare ca
2020/12/30 00:45:55 [INFO] generating a new CA key and certificate from CSR
2020/12/30 00:45:55 [INFO] generate received request
2020/12/30 00:45:55 [INFO] received CSR
2020/12/30 00:45:55 [INFO] generating key: rsa-2048
2020/12/30 00:45:56 [INFO] encoded CSR
2020/12/30 00:45:56 [INFO] signed certificate with serial number 529798847867094212963042958391637272775966762165
此时目录下会出现三个文件：
? → tree
├── ca-config.json #这是刚才的json
├── ca.csr
├── ca-csr.json #这也是刚才申请证书的json
├── ca-key.pem
├── ca.pem
这样 我们就生成了:
-
根证书文件: ca.pem -
根证书私钥: ca-key.pem -
根证书申请文件: ca.csr(csr 是不是 client ssl request?)
签发证书
创建harbor-csr.json,内容为：
{
"CN": "harbor",
"hosts": [
"example.net",
"*.example.net"
],
"key": {
"algo": "rsa",
"size": 2048
},
"names": [
{
"C": "US",
"ST": "CA",
"L": "San Francisco",
"O": "harbor",
"OU": "System"
}
]
}
使用之前的 CA 证书签发 harbor 证书：
? → cfssl gencert -ca=ca.pem -ca-key=ca-key.pem -config=ca-config.json -profile=harbor harbor-csr.json | cfssljson -bare harbor
2020/12/30 00:50:31 [INFO] generate received request
2020/12/30 00:50:31 [INFO] received CSR
2020/12/30 00:50:31 [INFO] generating key: rsa-2048
2020/12/30 00:50:31 [INFO] encoded CSR
2020/12/30 00:50:31 [INFO] signed certificate with serial number 372641098655462687944401141126722021767151134362
此时目录下会多几个文件：
? → tree -L 1
├── etcd.csr
├── etcd-csr.json
├── etcd-key.pem
├── etcd.pem
至此，harbor 的证书生成完成。
生成 Secret 资源
创建 Kubernetes 的 Secret 资源，且将证书文件导入：
-
- n：指定创建资源的 Namespace -
--from-file：指定要导入的文件地址
? → kubectl create ns harbor
? → kubectl -n harbor create secret generic harbor-tls --from-file=tls.crt=harbor.pem --from-file=tls.key=harbor-key.pem --from-file=ca.crt=ca.pem
查看是否创建成功：
? → kubectl -n harbor get secret harbor-tls
NAME TYPE DATA AGE
harbor-tls Opaque 3 1m
3. 使用 Ceph S3 为 Harbor chart 提供后端存储
创建 radosgw
如果你是通过 ceph-deploy 部署的，可以通过以下步骤创建 radosgw：
先安装 radosgw：
? → ceph-deploy install --rgw 172.16.7.1 172.16.7.2 172.16.7.3
然后创建 radosgw：
? → ceph-deploy rgw create 172.16.7.1 172.16.7.2 172.16.7.3
如果你是通过 cephadm 部署的，可以通过以下步骤创建 radosgw：
cephadm 将 radosgw 部署为管理特定领域和区域的守护程序的集合。例如，要在 172.16.7.1 上部署 1 个服务于 mytest 领域和 myzone 区域的 rgw 守护程序：
#如果尚未创建领域，请首先创建一个领域：
? → radosgw-admin realm create --rgw-realm=mytest --default
#接下来创建一个新的区域组：
? → radosgw-admin zonegroup create --rgw-zonegroup=myzg --master --default
#接下来创建一个区域：
? → radosgw-admin zone create --rgw-zonegroup=myzg --rgw-zone=myzone --master --default
#为特定领域和区域部署一组radosgw守护程序：
? → ceph orch apply rgw mytest myzone --placement="1 172.16.7.1"
查看服务状态：
? → ceph orch ls|grep rgw
rgw.mytest.myzone 1/1 5m ago 7w count:1 k8s01 docker.io/ceph/ceph:v15 4405f6339e35
测试服务是否正常：
? → curl -s http://172.16.7.1
正常返回如下数据：
<ListAllMyBucketsResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<Owner>
<ID>anonymousID>
<DisplayName>DisplayName>
Owner>
<Buckets>Buckets>
ListAllMyBucketsResult>
查看 zonegroup：
? → radosgw-admin zonegroup get
{
"id": "ed34ba6e-7089-4b7f-91c4-82fc856fc16c",
"name": "myzg",
"api_name": "myzg",
"is_master": "true",
"endpoints": [],
"hostnames": [],
"hostnames_s3website": [],

"endpoints": [],
"log_meta": "false",
"log_data": "false",
"bucket_index_max_shards": 11,
"read_only": "false",
"tier_type": "",
"sync_from_all": "true",
"sync_from": [],
"redirect_zone": ""
}
],
"placement_targets": [
{
"name": "default-placement",
"tags": [],
"storage_classes": [
"STANDARD"
]
}
],
"default_placement": "default-placement",
"realm_id": "e63c234c-e069-4a0d-866d-1ebdc69ec5fe",
"sync_policy": {
"groups": []
}
}
Create Auth Key
? → ceph auth get-or-create client.radosgw.gateway osd 'allow rwx' mon 'allow rwx' -o /etc/ceph/ceph.client.radosgw.keyring
分发 /etc/ceph/ceph.client.radosgw.keyring 到其它 radosgw 节点。
创建对象存储用户和访问凭证
-
Create a radosgw user for s3 access
? → radosgw-admin user create --uid="harbor" --display-name="Harbor Registry"
-
Create a swift user
? → adosgw-admin subuser create --uid=harbor --subuser=harbor:swift --access=full
-
Create Secret Key
? → radosgw-admin key create --subuser=harbor:swift --key-type=swift --gen-secret
记住 keys 字段中的 access_key & secret_key
创建存储桶（bucket）
首先需要安装 awscli：
? → pip3 install awscli -i https://pypi.tuna.tsinghua.edu.cn/simple
查看秘钥：
? → radosgw-admin user info --uid="harbor"|jq .keys
[
{
"user": "harbor",
"access_key": "VGZQY32LMFQOQPVNTDSJ",
"secret_key": "YZMMYqoy1ypHaqGOUfwLvdAj9A731iDYDjYqwkU5"
}
]
配置 awscli：
? → aws configure --profile=ceph
AWS Access Key ID [None]: VGZQY32LMFQOQPVNTDSJ
AWS Secret Access Key [None]: YZMMYqoy1ypHaqGOUfwLvdAj9A731iDYDjYqwkU5
Default region name [None]:
Default output format [None]: json
配置完成后，凭证将会存储到 ~/.aws/credentials：
? → cat ~/.aws/credentials
[ceph]
aws_access_key_id = VGZQY32LMFQOQPVNTDSJ
aws_secret_access_key = YZMMYqoy1ypHaqGOUfwLvdAj9A731iDYDjYqwkU5
配置将会存储到 ~/.aws/config：
? → cat ~/.aws/config
[profile ceph]
region = cn-hangzhou-1
output = json
创建存储桶（bucket）：
? → aws --profile=ceph --endpoint=http://172.16.7.1 s3api create-bucket --bucket harbor
查看存储桶（bucket）列表：
? → radosgw-admin bucket list
[
"harbor"
]
查看存储桶状态：
? → radosgw-admin bucket stats
[

3. 设置 Harbor 配置清单
由于我们需要通过 Helm 安装 Harbor 仓库，需要提前创建 Harbor Chart 的配置清单文件，里面是对要创建的应用 Harbor 进行一系列参数配置，由于参数过多，关于都有 Harbor Chart 都能够配置哪些参数这里就不一一罗列，可以通过访问 Harbor-helm 的 Github 地址[3] 进行了解。
下面描述下，需要的一些配置参数：
values.yaml
#入口配置，我只在内网使用，所以直接使用 cluserIP
expose:
type: clusterIP
tls:
### 是否启用 https 协议
enabled: true
certSource: secret
auto:
# The common name used to generate the certificate, it's necessary
# when the type isn't "ingress"
commonName: "harbor.example.net"
secret:
# The name of secret which contains keys named:
# "tls.crt" - the certificate
# "tls.key" - the private key
secretName: "harbor-tls"
# The name of secret which contains keys named:
# "tls.crt" - the certificate
# "tls.key" - the private key
# Only needed when the "expose.type" is "ingress".
notarySecretName: ""
## 如果Harbor部署在代理后，将其设置为代理的URL
externalURL: https://harbor.example.net
### Harbor 各个组件的持久化配置，并将 storageClass 设置为集群默认的 storageClass
persistence:
enabled: true
# Setting it to "keep" to avoid removing PVCs during a helm delete
# operation. Leaving it empty will delete PVCs after the chart deleted
# (this does not apply for PVCs that are created for internal database
# and redis components, i.e. they are never deleted automatically)
resourcePolicy: "keep"
persistentVolumeClaim:
registry:
# Use the existing PVC which must be created manually before bound,
# and specify the "subPath" if the PVC is shared with other components
existingClaim: ""
# Specify the "storageClass" used to provision the volume. Or the default
# StorageClass will be used(the default).
# Set it to "-" to disable dynamic provisioning
storageClass: "csi-rbd-sc"
subPath: ""
accessMode: ReadWriteOnce
size: 100Gi
chartmuseum:
existingClaim: ""
storageClass: "csi-rbd-sc"
subPath: ""
accessMode: ReadWriteOnce
size: 5Gi
jobservice:
existingClaim: ""
storageClass: "csi-rbd-sc"
subPath: ""
accessMode: ReadWriteOnce
size: 5Gi
# If external database is used, the following settings for database will
# be ignored
database:
existingClaim: ""
storageClass: "csi-rbd-sc"
subPath: ""
accessMode: ReadWriteOnce
size: 5Gi
# If external Redis is used, the following settings for Redis will
# be ignored
redis:
existingClaim: ""
storageClass: "csi-rbd-sc"
subPath: ""
accessMode: ReadWriteOnce
size: 5Gi
trivy:
existingClaim: ""
storageClass: "csi-rbd-sc"
subPath: ""
accessMode: ReadWriteOnce
size: 5Gi
### 默认用户名 admin 的密码配置，注意：密码中一定要包含大小写字母与数字
harborAdminPassword: "Mydlq123456"
### 设置日志级别

4. 安装 Harbor
添加 Helm 仓库
? → helm repo add harbor https://helm.goharbor.io
部署 Harbor
? → helm install harbor harbor/harbor -f values.yaml -n harbor
查看应用是否部署完成
? → kubectl -n harbor get pod
NAME READY STATUS RESTARTS AGE

harbor-harbor-registry-5b6cbfb4cf-42fm9 2/2 Running 0 3m
harbor-harbor-trivy-0 1/1 Running 0 3m
Host 配置域名
接下来配置 Hosts，客户端想通过域名访问服务，必须要进行 DNS 解析，由于这里没有 DNS 服务器进行域名解析，所以修改 hosts 文件将 Harbor 指定 clusterIP 和自定义 host 绑定。首先查看 nginx 的 clusterIP：
? → kubectl -n harbor get svc harbor-harbor-nginx
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
harbor-harbor-nginx ClusterIP 10.109.50.142
80/TCP,443/TCP 22h
打开主机的 Hosts 配置文件，往其加入下面配置：
10.109.50.142 harbor.example.net
如果想在集群外访问，建议将 Service nginx 的 type 改为 nodePort 或者通过 ingress 来代理。当然，如果你在集群外能够直接访问 clusterIP，那更好。
输入地址 https://harbor.example.net 访问 Harbor 仓库。
-
用户：admin -
密码：Mydlq123456 (在安装配置中自定义的密码)
进入后可以看到 Harbor 的管理后台：
5. 服务器配置镜像仓库
对于 Containerd 来说，不能像 docker 一样 docker login 登录到镜像仓库，需要修改其配置文件来进行认证。/etc/containerd/config.toml 需要添加如下内容：
[plugins."io.containerd.grpc.v1.cri".registry]
[plugins."io.containerd.grpc.v1.cri".registry.mirrors]
...
[plugins."io.containerd.grpc.v1.cri".registry.configs]
[plugins."io.containerd.grpc.v1.cri".registry.configs."harbor.example.net".tls]
insecure_skip_verify = true
[plugins."io.containerd.grpc.v1.cri".registry.configs."harbor.example.net".auth]
username = "admin"
password = "Mydlq123456"
由于 Harbor 是基于 Https 的，理论上需要提前配置 tls 证书，但可以通过 insecure_skip_verify 选项跳过证书认证。
当然，如果你想通过 Kubernetes 的 secret 来进行用户验证，配置还可以精简下：
[plugins."io.containerd.grpc.v1.cri".registry]
[plugins."io.containerd.grpc.v1.cri".registry.mirrors]
...
[plugins."io.containerd.grpc.v1.cri".registry.configs]
[plugins."io.containerd.grpc.v1.cri".registry.configs."harbor.example.net".tls]
insecure_skip_verify = true
Kubernetes 集群使用 docker-registry 类型的 Secret 来通过镜像仓库的身份验证，进而拉取私有映像。所以需要创建 Secret，命名为 regcred：
? → kubectl create secret docker-registry regcred \
--docker-server=<你的镜像仓库服务器> \
--docker-username=<你的用户名> \
--docker-password=<你的密码> \
--docker-email=<你的邮箱地址>
然后就可以在 Pod 中使用该 secret 来访问私有镜像仓库了，下面是一个示例 Pod 配置文件：
apiVersion: v1
kind: Pod
metadata:
name: private-reg
spec:
containers:
- name: private-reg-container
image:
imagePullSecrets:
- name: regcred
如果你不嫌麻烦，想更安全一点，那就老老实实将 CA、证书和秘钥拷贝到所有节点的 /etc/ssl/certs/ 目录下。/etc/containerd/config.toml 需要添加的内容更多一点：
[plugins."io.containerd.grpc.v1.cri".registry]
[plugins."io.containerd.grpc.v1.cri".registry.mirrors]
...
[plugins."io.containerd.grpc.v1.cri".registry.configs]
[plugins."io.containerd.grpc.v1.cri".registry.configs."harbor.example.net".tls]
ca_file = "/etc/ssl/certs/ca.pem"
cert_file = "/etc/ssl/certs/harbor.pem"
key_file = "/etc/ssl/certs/harbor-key.pem"
至于 Docker 的配置方式，大家可以自己去搜一下，这里就跳过了，谁让它现在不受待见呢。
6. 测试功能
这里为了测试推送镜像，先下载一个用于测试的 helloworld 小镜像，然后推送到 harbor.example.net 仓库：
### 拉取 Helloworld 镜像
