harbor部署（helm chat）

一、安装docker-ce

docker-ce二进制包下载地址
二进制包下载地址：https://download.docker.com/linux/static/stable/x86_64/

#解压
tar xf docker-20.10.15.tgz 
#拷贝二进制文件
cp docker/* /usr/bin/
#创建containerd的service文件,并且启动
cat >/etc/systemd/system/containerd.service <<EOF

二、部署harbor

下载链接：https://github.com/goharbor/harbor/releases/download/v2.6.2/harbor-offline-installer-v2.6.2.tgz
生成证书：

# 生成ca私钥
root@harbor:~/apps/harbor/certs# openssl genrsa -out ca.key 4096
Generating RSA private key, 4096 bit long modulus (2 primes)
..................................................++++
.....................................................................++++
e is 65537 (0x010001)
#生成ca证书
root@harbor:~/apps/harbor/certs# ls
ca.key
root@harbor:~/apps/harbor/certs# openssl req -x509 -new -nodes -sha512 -days 3650 -subj "/C=CN/ST=Beijing/L=Beijing/O=example/OU=Personal/CN=harbor.whyxx.net" -key ca.key -out ca.crt
root@harbor:~/apps/harbor/certs# ls
ca.crt  ca.key
# 生成服务端key
root@harbor:~/apps/harbor/certs# openssl genrsa -out harbor.whyxx.net.key 4096
Generating RSA private key, 4096 bit long modulus (2 primes)
.....................................................................++++
............................................................................................................................................................................................................................................................++++
e is 65537 (0x010001)
root@harbor:~/apps/harbor/certs# ls
ca.crt  ca.key  harbor.whyxx.net.key
# 生成证书签署请求文件
root@harbor:~/apps/harbor/certs# openssl req -sha512 -new -subj "/C=CN/ST=Beijing/L=Beijing/O=example/OU=Personal/CN=harbor.whyxx.net" -key harbor.whyxx.net.key -out harbor.whyxx.net.csr
root@harbor:~/apps/harbor/certs# ls
ca.crt  ca.key  harbor.whyxx.net.csr  harbor.whyxx.net.key
# 新建扩展文件
root@harbor:~/apps/harbor/certs# cat v3.ext 
authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
extendedKeyUsage = serverAuth
subjectAltName = @alt_names

[alt_names]
DNS.1=harbor.whyxx.net
DNS.2=harbor
DNS.3=ks-allinone
# 使用根证书、根私钥签署服务器证书
root@harbor:~/apps/harbor/certs# openssl x509 -req -sha512 -days 3650 -extfile v3.ext -CA ca.crt -CAkey ca.key -CAcreateserial -in harbor.whyxx.net.csr -out harbor.whyxx.net.crt
Signature ok
subject=C = CN, ST = Beijing, L = Beijing, O = example, OU = Personal, CN = harbor.whyxx.net
Getting CA Private Key
root@harbor:~/apps/harbor/certs# ls
ca.crt  ca.srl                harbor.whyxx.net.csr  v3.ext
ca.key  harbor.whyxx.net.crt  harbor.whyxx.net.key
# 更新部署证书
root@harbor:/usr/local/share/ca-certificates# cp /root/apps/harbor/certs/harbor.whyxx.net.crt .
root@harbor:/usr/local/share/ca-certificates# ls
harbor.whyxx.net.crt
root@harbor:/usr/local/share/ca-certificates# update-ca-certificates 
Updating certificates in /etc/ssl/certs...
rehash: warning: skipping ca-certificates.crt,it does not contain exactly one certificate or CRL
1 added, 0 removed; done.
Running hooks in /etc/ca-certificates/update.d...
done.

将csr转换成cert，给予docker使用

openssl x509 -inform PEM -in harbor.whyxx.net.crt -out harbor.whyxx.net.cert

修改harbor配置文件：

cp harbor.yml.tmpl harbor.yml
image.png

安装harbor:

root@harbor:~/apps/harbor# ls
LICENSE  common.sh             harbor.yml       install.sh
certs    harbor.v2.6.2.tar.gz  harbor.yml.tmpl  prepare
root@harbor:~/apps/harbor# ./install.sh --help

Note: Please set hostname and other necessary attributes in harbor.yml first. DO NOT use localhost or 127.0.0.1 for hostname, because Harbor needs to be accessed by external clients.
Please set --with-notary if needs enable Notary in Harbor, and set ui_url_protocol/ssl_cert/ssl_cert_key in harbor.yml bacause notary must run under https. 
Please set --with-trivy if needs enable Trivy in Harbor
Please set --with-chartmuseum if needs enable Chartmuseum in Harbor
# 安装
root@harbor:~/apps/harbor# ./install.sh --with-notary --with-chartmuseum --with-trivy

[Step 0]: checking if docker is installed ...

Note: docker version: 20.10.12

[Step 1]: checking docker-compose is installed ...

Note: docker-compose version: 1.25.0

[Step 2]: loading Harbor images ...
93d5db33d7f0: Loading layer  37.72MB/3
................

同步证书：

root@harbor:/etc/docker# mkdir certs.d/harbor.whyxx.net -p
root@harbor:~/apps/harbor/certs# cp ca.crt harbor.whyxx.net.crt harbor.whyxx.net.key /etc/docker/certs.d/harbor.whyxx.net/

添加hosts解析：

root@harbor:~/apps/harbor/certs# cat /etc/hosts
127.0.0.1 localhost
192.168.50.10 master01
192.168.50.11 master02
192.168.50.12 master03
192.168.50.13 etcd01
192.168.50.14 etcd02
192.168.50.15 etcd03
192.168.50.16 node01
192.168.50.17 node02
192.168.50.18 node03
192.168.50.19 harbor.whyxx.net

重启docker

root@harbor:~/apps/harbor/certs# systemctl daemon-reload
root@harbor:~/apps/harbor/certs# systemctl restart docker

访问：
https://192.168.50.19

三、使用harbor存储docker镜像

四、使用harbor存储helm chat

4.1、安装 helm

下载地址：https://get.helm.sh/helm-v3.10.2-linux-amd64.tar.gz
cp helm /usr/bin/

4.2、在harbor ui 界面上创建仓库
4.3、helm增加repo

root@master01:/etc/docker/certs/harbor.whyxx.net# helm repo add --ca-file /etc/docker/certs/harbor.whyxx.net/ca.crt --cert-file /etc/docker/certs/harbor.whyxx.net/harbor.whyxx.net.cert --key-file /etc/docker/certs/harbor.whyxx.net/harbor.whyxx.net.key --username admin --password 123456 chartrepo https://harbor.whyxx.net/chartrepo/chartrepo
"chartrepo" has been added to your repositories
root@master01:/etc/docker/certs/harbor.whyxx.net# helm repo update
Hang tight while we grab the latest from your chart repositories...
...Successfully got an update from the "chartrepo" chart repository
Update Complete. ⎈Happy Helming!⎈
root@master01:/etc/docker/certs/harbor.whyxx.net# helm repo list
NAME        URL                                         
chartrepo   https://harbor.whyxx.net/chartrepo/chartrepo

4.4、向harbor仓库push一个应用

root@master01:~/apps/helm/chat# helm create wh-helm
Creating wh-helm
root@master01:~/apps/helm/chat/wh-helm/templates# cat <<EOF > configmap.yaml
> apiVersion: v1
> kind: ConfigMap
> metadata:
>   name: helm-configmap
> data:
>   myvalue: "Hello World"
> EOF
root@master01:~/apps/helm/chat# helm package wh-helm/
Successfully packaged chart and saved it to: /root/apps/helm/chat/wh-helm-0.1.0.tgz
root@master01:~/apps/helm/chat# ls
wh-helm  wh-helm-0.1.0.tgz
# 安装 push 插件
root@master01:~/apps/helm/chat# helm plugin install https://github.com/chartmuseum/helm-push
Downloading and installing helm-push v0.10.3 ...
https://github.com/chartmuseum/helm-push/releases/download/v0.10.3/helm-push_0.10.3_linux_amd64.tar.gz
Installed plugin: cm-push
# 推送
root@master01:~/apps/helm/chat# helm cm-push --ca-file /etc/docker/certs/harbor.whyxx.net/ca.crt --cert-file /etc/docker/certs/harbor.whyxx.net/harbor.whyxx.net.cert --key-file /etc/docker/certs/harbor.whyxx.net/harbor.whyxx.net.key --username admin --password 123456 wh-helm-0.1.0.tgz chartrepo 
Pushing wh-helm-0.1.0.tgz to chartrepo...
Done.

4.5、安装与更新

root@master01:~# helm install wh-test chartrepo/wh-test  # 这还可以这样写 helm install chartrepo/wh-test --generate-name
NAME: wh-test
