docker的基本命令

docker images 镜像列表

docker pull xxx:xx 拉取镜像

docker stop containerName 停止容器

docker rm containerName 删除容器

docker rmi abc 删除镜像，镜像ID三个首字母

1 安装nginx

参考自这里

安装docker：apt install docker.io 下载nginx镜像：docker pull nginx:1.22.0

1.22.0: Pulling from library/nginx
bd159e379b3b: Pull complete
265da2307f4a: Pull complete

Digest: sha256:f0d28f2047853cbc10732d6eaa1b57f1f4db9b017679b9fd7966b6a2f9ccc2d1
Status: Downloaded newer image for nginx:1.22.0
docker.io/library/nginx:1.22.0

创建nginx宿主配置文件：mkdir /root/docker-nginx

运行docker：

tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      11725/docker-proxy

创建容器并运行：

docker run --name nginx -p 80:80 -d nginx:1.22.0

把nginx内部文件拷贝到宿主：

root@daniel:~# docker cp nginx:/etc/nginx/nginx.conf /root/docker-nginx/
root@daniel:~# docker cp nginx:/etc/nginx/conf.d/ /root/docker-nginx/conf.d/
root@daniel:~# docker cp nginx:/usr/share/nginx/html/ /root/docker-nginx/html/
root@daniel:~# docker cp nginx:/var/log/nginx/ /root/docker-nginx/logs/

将nginx配置文件等打包，以后可以作为模板复用： tar -czvf docker-nginx.tar.gz docker-nginx/*

停止docker：docker stop nginx

删除容器：docker rm nginx

创建容器并运行：

docker run -p 80:80 \
-v /root/docker-nginx/nginx.conf:/etc/nginx/nginx.conf \
-v /root/docker-nginx/logs:/var/log/nginx \
-v /root/docker-nginx/html:/usr/share/nginx/html \
-v /root/docker-nginx/conf.d:/etc/nginx/conf.d \
-v /etc/localtime:/etc/localtime \
--name nginx \
--restart=always \
-d nginx:1.22.0

2 安装hugo

参考自这里 拉取镜像：docker pull klakegg/hugo:latest-ext

latest-ext: Pulling from klakegg/hugo
b85a868b505f: Pull complete
0dbfd71332b3: Pull complete
76a604ef4c8f: Pull complete

ca0d4322cdfd: Pull complete

0a89b068afa8: Pull complete
Digest: sha256:a82da170159c84e5a59a9fd237da8c063bc062c72d6023afd1a4e3a0c40a9b4e
Status: Downloaded newer image for klakegg/hugo:latest-ext
docker.io/klakegg/hugo:latest-ext
root@daniel:~# docker images
REPOSITORY     TAG          IMAGE ID       CREATED        SIZE
klakegg/hugo   latest-ext   13ef2cb044b7   2 months ago   963MB

建目录：mkdirs -p /root/docker-hugo，进入目录。

下面这个创建命令一直不成功。docker run --rm -it -v $(pwd):/src klakegg/hugo:latest-ext "new site daniel"

于是用下面的：

root@daniel:~/docker-hugo# docker run --rm -it -v $(pwd):/src klakegg/hugo:latest-ext shell
hugo:/src$ hugo new site roadl.com
Congratulations! Your new Hugo site is created in /src/roadl.com.

Just a few more steps and you're ready to go:

1. Download a theme into the same-named folder.
   Choose a theme from https://themes.gohugo.io/ or
   create your own with the "hugo new theme <THEMENAME>" command.
2. Perhaps you want to add some content. You can add single files
   with "hugo new <SECTIONNAME>/<FILENAME>.<FORMAT>".
3. Start the built-in live server via "hugo server".

Visit https://gohugo.io/ for quickstart guide and full documentation.

成功！

创建博文：cd roadl.com && hugo new posts/first_post.md

然后就能启动了，下列是Developer模式：

docker run --rm -it \
  -v $(pwd)/roadl.com:/src \
  -p 1313:1313 \
  klakegg/hugo:latest-ext \
  server

后来用了安装包的方式安装了hugo，后台常驻运行的命令行是：

hugo server --watch --renderToDisk &

下载主题：git clone https://github.com/dillonzq/LoveIt.git themes/loveit

备份主题配置以及替换配置：cp config.toml config.toml.bak && cp themes/loveit/config.toml .

引用主题：echo 'theme = "minimal"' >> config.toml

这时就可以访问到网站了：http://39.98.41.150:1313/

后来，使用了yinyang的主题，链接在这里，并对样式进行了一些调整，比如：

  • 加了一个线条
  • 调整了site-footer的边距等
  • 下方露出ICP备案

3 安装与使用docker compose安装gitlab

项目地址在这里，最新版本2.16.0(2023/02/22)

  • 在线下载：

参考自这里

sudo curl -L https://get.daocloud.io/docker/compose/releases/download/v2.16.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   425  100   425    0     0    557      0 --:--:-- --:--:-- --:--:--   557
100 45.4M  100 45.4M    0     0  11.8M      0  0:00:03  0:00:03 --:--:-- 12.2M

命令行相当于这样：sudo curl -L https://get.daocloud.io/docker/compose/releases/download/v2.16.0/docker-compose-`uname -s-uname -m` -o /usr/local/bin/docker-compose

还有一个地址是：https://github.com/docker/compose/releases/download/v2.16.0/docker-compose-linux-x86_64

  • 添加执行权限: sudo chmod +x /usr/local/bin/docker-compose

在/root/docker-compose/gitlab下编辑脚本文件docker-compose.yml，内容如下：

version: "3.6"
services:
  gitlab:
    image: gitlab/gitlab-ce:latest
    restart: always
    privileged: true
    ports:
      - '2222:80'
      - '2443:443'
      - '222:22'
    volumes:
      - '~/data:/var/opt/gitlab'
      - '~/logs:/var/log/gitlab'
      - '~/config:/etc/gitlab'

然后运行命令，会执行下载，大小大致在1.2G：
