  • 1、docker pull mysql报错 ...Error response from daemon: Get https://registry-1.docker.io/v2/: proxyconnect tcp: tls: first record does not look like a TLS handshake 2、查看代理配置 [root@k8s

    1、docker pull mysql报错

    [root@k8s docker.service.d]# docker pull mysql
    Using default tag: latest
    Error response from daemon: Get https://registry-1.docker.io/v2/: proxyconnect tcp: tls: first record does not look like a TLS handshake

    2、查看代理配置

    [root@k8s docker.service.d]# sudo systemctl show --property=Environment docker
    Environment=HTTP_PROXY=http://proxy.scott.net:8081 HTTPS_PROXY=https://proxy.scott.net:8081 NO_PROXY=localhost,127.0.0.1
    [root@k8s docker.service.d]# 

    3、代理配置是参考https://docs.docker.com/config/daemon/systemd/

    3.1 Create a systemd drop-in directory for the docker service

    sudo mkdir -p /etc/systemd/system/docker.service.d

    3.2 Create a file named /etc/systemd/system/docker.service.d/http-proxy.conf that adds the HTTP_PROXY environment variable:

    [Service]
    Environment="HTTP_PROXY=http://proxy.example.com:80"

    If you are behind an HTTPS proxy server, set the HTTPS_PROXY environment variable:

    [Service]
    Environment="HTTPS_PROXY=https://proxy.example.com:443"

    Multiple environment variables can be set; to set both a non-HTTPS and a HTTPs proxy;

    [Service]
    Environment="HTTP_PROXY=http://proxy.example.com:80"
    Environment="HTTPS_PROXY=https://proxy.example.com:443"

    3.3 

    If you have internal Docker registries that you need to contact without proxying you can specify them via the NO_PROXY environment variable.

    The NO_PROXY variable specifies a string that contains comma-separated values for hosts that should be excluded from proxying. These are the options you can specify to exclude hosts:

    • IP address prefix (1.2.3.4)
    • Domain name, or a special DNS label (*)
    • A domain name matches that name and all subdomains. A domain name with a leading “.” matches subdomains only. For example, given the domains foo.example.com and example.com:
      • example.com matches example.com and foo.example.com, and
      • .example.com matches only foo.example.com
    • A single asterisk (*) indicates that no proxying should be done
    • Literal port numbers are accepted by IP address prefixes (1.2.3.4:80) and domain names (foo.example.com:80)

    Config example:

    [Service]
    Environment="HTTP_PROXY=http://proxy.example.com:80"
    Environment="HTTPS_PROXY=https://proxy.example.com:443"
    Environment="NO_PROXY=localhost,127.0.0.1,docker-registry.example.com,.corp"

    3.4 Flush changes and restart Docker

    sudo systemctl daemon-reload
    sudo systemctl restart docker

    3.5 Verify that the configuration has been loaded and matches the changes you made, for example:

    sudo systemctl show --property=Environment docker
        
    Environment=HTTP_PROXY=http://proxy.example.com:80 HTTPS_PROXY=https://proxy.example.com:443 NO_PROXY=localhost,127.0.0.1,docker-registry.example.com,.corp

    4、查看docker info 

    [root@k8s ~]# docker info
    Client:
     Debug Mode: false
    
    Server:
     Containers: 0
      Running: 0

    5、修改配置文件/etc/systemd/system/docker.service.d/http-proxy.conf,去掉HTTPS_PROXY

    修改前

    [root@k8s docker.service.d]# cat https-proxy.conf 
    [Service]
    Environment="HTTP_PROXY=http://proxy.scott.net:8081/" "HTTPS_PROXY=https://proxy.scott.net:8081/" "NO_PROXY=localhost,127.0.0.1"

    修改后

    [root@k8s docker.service.d]# cat https-proxy.conf 
    [Service]
    Environment="HTTP_PROXY=http://proxy.scott.net:8081/" "NO_PROXY=localhost,127.0.0.1"

    docker info

    [root@k8s docker.service.d]# docker info
    Client:
     Debug Mode: false
    
    Server:

     Registry Mirrors:

     Live Restore Enabled: false

    6、Flush changes and restart Docker

    sudo systemctl daemon-reload
    sudo systemctl restart docker

    7、查看docker代理

    [root@k8s docker.service.d]# sudo systemctl show --property=Environment docker
    Environment=HTTP_PROXY=http://proxy.scott.net:8081/ NO_PROXY=localhost,127.0.0.1

    8、pull

    [root@k8s docker.service.d]# docker pull mysql
    Using default tag: latest
    latest: Pulling from library/mysql

    生产环境linux部分服务器是没有外网地址,所以都是通过代理配置上网的。

    但是今天发现linux配置完代理后,可以上网了,但是获取docker镜像时,提示 Get https://registry-1.docker.io/v2/  proxyconnect tcp: tls: oversized record received with length 20527

     

    因为没有外网,所以第一时间想到的是代理配置的问题。

    通过搜索了解到,docker有自身的代理配置,如下

    #创建一个代理配置文件
    touch /etc/systemd/system/docker.service.d/http-proxy.conf 
    # 写入内容
    [Service]
    Environment="HTTP_PROXY=http://[proxy-addr]:[proxy-port]/" "HTTPS_PROXY=http://[proxy-addr]:[proxy-port]/" "NO_PROXY=localhost,127.0.0.1"
    
    # 注意,这个的HTTPS_PROXY也要设置为和HTTP_PROXY
    # 更新配置
    systemctl daemon-reload
    
    # 重启docker
    systemctl restart docker

    再次获取镜像成功了。

    错误原因:

         https_proxy中错误使用了https的地址

    1. 检查https_proxy设置:

    echo $https_proxy

    如果输出的结果中是https开头的url地址

    2. 解决办法

    export https_proxy=http://agent.youwebsite.com:port

    3.再次重试git pull即可

    注意:设置https_proxy的终端应该和git  pull的终端是同一个。
