上一节我们创建了一个bucket , 不过你是否注意到一个细节, 我们使用的是http
实际项目中你往往需要通过 https
这里将https设置为true
lizhedeMacBook-Pro:~ lizhe$ cat ~/.s3cfg
# Setup endpoint
host_base = localhost:9090
host_bucket = localhost:9090
bucket_location = us-east-1
use_https = True
# Setup access keys
access_key = admin
secret_key = admin123456
# Enable S3 v4 signature APIs
signature_v2 = False
lizhedeMacBook-Pro:~ lizhe$ 再尝试创建发现得到了错误
lizhedeMacBook-Pro:~ lizhe$ s3cmd mb s3://mybuckethttps
ERROR: SSL certificate verification failure: [SSL: UNKNOWN_PROTOCOL] unknown protocol (_ssl.c:590)
lizhedeMacBook-Pro:~ lizhe$ 这里要让 minio 支持 https , 需要先生成本地证书, 这里我们简单一点, 使用go

}这里 cert.pem 是公钥, key.pem是私钥, minio 只支持 pem 格式
为了让minio服务器可以打开https服务, 需要将证书放在
~/.minio/certs
当然你可以选择直接mount路径到 docker 容器, 也可以选择拷贝, 这里我使用 拷贝 的方案
lizhedeMacBook-Pro:ca lizhe$ pwd
/Users/lizhe/Documents/DEV/projects/golang/ca
lizhedeMacBook-Pro:ca lizhe$
lizhedeMacBook-Pro:ca lizhe$ go run generate_cert.go -ca --host "localhost"
2019/03/11 16:49:57 wrote cert.pem

lizhedeMacBook-Pro:ca lizhe$
lizhedeMacBook-Pro:ca lizhe$ cp key.pem private.key
lizhedeMacBook-Pro:ca lizhe$ cp cert.pem public.crt
lizhedeMacBook-Pro:ca lizhe$
lizhedeMacBook-Pro:ca lizhe$ ls
cert.pem generate_cert.go key.pem private.key public.crt
lizhedeMacBook-Pro:ca lizhe$
lizhedeMacBook-Pro:ca lizhe$ docker run -p 9090:9000 --name studyminio -d -e MINIO_ACCESS_KEY=admin -e MINIO_SECRET_KEY=admin123456 minio/minio server /data

lizhedeMacBook-Pro:ca lizhe$ docker restart studyminio
studyminio
lizhedeMacBook-Pro:ca lizhe$ 
NOTE: Location of custom certs directory can be specified using --certs-dir command line option.
然后就可以通过 https://localhost:9090/ 来访问 minio 服务器了
当然 s3cmd 也可以使用了
lizhedeMacBook-Pro:ca lizhe$ cd /Users/lizhe/Documents/DEV/projects/golang/ca
lizhedeMacBook-Pro:ca lizhe$ ls
cert.pem generate_cert.go key.pem private.key public.crt
lizhedeMacBook-Pro:ca lizhe$ cat ~/.s3cfg

# Enable S3 v4 signature APIs
signature_v2 = False
lizhedeMacBook-Pro:ca lizhe$ s3cmd mb --no-check-certificate s3://mybucket1
