为github的docker源提速

下载zlib（github上的）非常幸苦，速度极慢

找到了大神的文章：加速docker pull

有什么用

为github的docker源提速，比如：

ghcr.io/zlib-searcher/zlib-searcher:latest

ghcr.io/puzzithinker/zlib-searcher:master

怎么用

  1. 配置http-proxy.conf

mkdir -p /etc/systemd/system/docker.service.d
vim /etc/systemd/system/docker.service.d/http-proxy.conf
[Service]
Environment="HTTP_PROXY=http://192.168.1.1:7890"
  1. 配置https-proxy.conf

vim /etc/systemd/system/docker.service.d/https-proxy.conf
[Service]
Environment="HTTPS_PROXY=http://192.168.1.1:7890"
#这个设置是难点，踩坑折腾了半小时左右，一直监控着clash.meta的UI，docker pull过程到底有没有走proxy，设置对了以后，速度果然一下子，嗖.....
  1. 重启服务

2
sudo systemctl daemon-reload
sudo systemctl restart docker
  1. 监控一下是否正常走了设置的代理

You will need to save the Docker image as a tar file:

> docker save -o <path for generated tar file> <image name>
Then copy your image to a new system with regular file transfer tools such as cp, scp, or rsync (preferred for big files). After that you will have to load the image into Docker:

> docker load -i <path to image tar file>
You should add filename (not just directory) with -o, for example:

> docker save -o c:/myfile.tar centos:16
PS: You may need to sudo all commands.

将docker内文件拷贝到本地文件夹内

  docker cp 容器Id或name:容器内路径 本地文件夹路径
  docker cp containername:/usr/share/nginx/html /volume2/KingchuxingSSD512G/docker/compose/it-tools/html

反之亦然

NAS中无法使用该文方案

失败错误：

环境NAS中 docker pull alfg/nginx-rtmp

docker pull 如何走代理?

执行像上面那样的步骤

sudo systemctl daemon-reload
sudo systemctl restart docker

2
sudo systemctl restart docker           
Failed to restart docker.service: Unit docker.service failed to load: No such file or directory.

暂时放弃了该NAS中的docker，目前无法解决这个错误。（等待第二天自动重启后查看状态）

  • 切换到debian中可以正常pull（已经打了这个‘补丁’）

    /www/server/panel/data/compose/

  • 或者 在docker-compose文件中 使用国内可用的镜像地址

    • 比如：registry.cn-hangzhou.aliyuncs.com/ossrs/srs:5

Docker 通过ffmpeg将rtsp转码为rtmp进行播放

整个流程说明：rtsp转rtmp直播.md

切换docker镜像到docker run -d -p 1935:1935 -p 8080:8080 alqutami/rtmp-hls

        image: alqutami/rtmp-hls

配置 nginx-hls.conf

是否需要做配置？

上面这个方案的docker pull成功，但是无法正常启动；切换：

使用镜像自带的players播放

  • To play RTMP content (requires Flash): http://localhost:8080/players/rtmp.html
  • To play HLS content: http://localhost:8080/players/hls.html
  • To play HLS content using hls.js library: http://localhost:8080/players/hls_hlsjs.html
  • To play DASH content: http://localhost:8080/players/dash.html
  • To play RTMP and HLS contents on the same page: http://localhost:8080/players/rtmp_hls.html
