二、本次实践规划

2.1 本地环境规划

本次实践为个人测试环境，操作系统版本为|Ubuntu 22.04.1。

hostname	IP地址	操作系统版本	内核版本	Docker版本	镜像版本
jeven01	192.168.3.88	Ubuntu 22.04.1 LTS	5.15.0-119-generic	24.0.7	2.5

2.2 本次实践介绍

1.本次实践部署环境为个人测试环境，生产环境请谨慎； 2.在Docker环境下部署Szurubooru图像板应用。

三、本地环境检查

3.1 检查Docker服务状态

检查Docker服务是否正常运行，确保Docker正常运行。

root@ubuntu-001:~# systemctl status docker
● docker.service - Docker Application Container Engine
     Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
     Active: active (running) since Sun 2024-09-29 08:29:36 UTC; 18min ago
TriggeredBy: ● docker.socket
       Docs: https://docs.docker.com
   Main PID: 5227 (dockerd)
      Tasks: 123
     Memory: 272.5M
        CPU: 9.692s
     CGroup: /system.slice/docker.service
             ├─5227 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock

3.2 检查Docker版本

检查Docker版本

root@ubuntu-001:~# docker -v
Docker version 24.0.7, build 24.0.7-0ubuntu2~22.04.1

3.3 检查docker compose 版本

检查Docker compose版本，确保2.0以上版本。

root@ubuntu-001:~#  docker compose version
Docker Compose version v2.19.1

四、下载Szurubooru镜像

拉取Szurubooru镜像，其中镜像szurubooru两个镜像版本使用的为2.5。

docker pull  szurubooru/server:2.5
docker pull  szurubooru/client:2.5
docker pull  postgres:11-alpine

五、部署Szurubooru应用

5.1 创建部署目录

• 创建部署目录

mkdir -p /data/szurubooru && cd /data/szurubooru

• 设置目录权限

chmod -R 777 /data/szurubooru/

5.2 编辑config.yaml文件

编辑config.yaml配置文件，内容所辖：

vim config.yaml

# rather than editing this file, it is strongly suggested to create config.yaml
# and override only what you need.

# shown in the website title and on the front page
name: szurubooru
# full url to the homepage of this szurubooru site, with no trailing slash
domain: # example: http://example.com
# used to salt the users' password hashes and generate filenames for static content
secret: change

# Delete thumbnails and source files on post delete
# Original functionality is no, to mitigate the impacts of admins going
# on unchecked post purges.
delete_source_files: no

thumbnails:
    avatar_width: 300
    avatar_height: 300
    post_width: 300
    post_height: 300

# settings used to download files from the web on behalf of the api users
user_agent:
max_dl_filesize: 25.0E+6 # maximum filesize limit in bytes

# automatically convert animated GIF uploads to video formats
convert:
   gif:
     to_webm: false
     to_mp4: false

# allow posts to be uploaded even if some image processing errors occur
allow_broken_uploads: false

# used to send password reset e-mails
smtp:
    host: # example: localhost
    port: # example: 25
    user: # example: bot
    pass: # example: groovy123
    from: # example: noreply@example.com
    # if host is left empty the password reset feature will be disabled,
    # in which case it is recommended to fill contactEmail so that users
    # know who to contact when they want to reset their password

contact_email: # example: bob@example.com. Meant for manual password reset procedures

enable_safety: yes

tag_name_regex: ^\S+$
tag_category_name_regex: ^[^\s%+#/]+$

pool_name_regex: ^\S+$

# customize them, make sure to update the instructions in the registration form
# template as well.
password_regex: '^.{5,}$'
user_name_regex: '^[a-zA-Z0-9_-]{1,32}$'

#data_dir: /var/www/data
## usage: schema://user:password@host:port/database_name
## example: postgres://szuru:dog@localhost:5432/szuru_test
#database:

5.3 编辑.env文件

在部署目录下，新建及编辑.env文件

vim  .env

# Database credentials
POSTGRES_USER=jeven
POSTGRES_PASSWORD=jeven
# This shows up on the homescreen, indicating build information
BUILD_INFO=latest

# Port to expose HTTP service
# Set to 127.0.0.1:8080 if you wish to reverse-proxy the docker's port,
# otherwise the port specified here will be publicly accessible
PORT=8080

# How many waitress threads to start
# 4 is the default amount of threads. If you experience performance
# degradation with a large number of posts, increasing this may
# improve performance, since waitress is most likely clogging up with Tasks.
THREADS=4

# URL base to run szurubooru under
# See "Additional Features" section in INSTALL.md
BASE_URL=/

# Directory to store image data
MOUNT_DATA=/data/szurubooru/data

# Directory to store database files
MOUNT_SQL=/data/szurubooru/sql

5.4 编辑部署文件

在/data/szurubooru`目录下，创建docker-compose.yaml文件，宿主机映射端口可自行修改，注意防止端口冲突。

vim docker-compose.yaml

## Example Docker Compose configuration
##
## Use this as a template to set up docker-compose, or as guide to set up other
## orchestration services
version: '2'

services:

  server:
    image: szurubooru/server:2.5
    depends_on:
      - sql
    environment:
      ## These should be the names of the dependent containers listed below,
      ## or FQDNs/IP addresses if these services are running outside of Docker
      POSTGRES_HOST: sql
      ## Credentials for database:
      POSTGRES_USER:
      POSTGRES_PASSWORD:
      ## Commented Values are Default:
      #POSTGRES_DB: defaults to same as POSTGRES_USER
      #POSTGRES_PORT: 5432
      #LOG_SQL: 0 (1 for verbose SQL logs)
      THREADS:
    volumes:
      - "${MOUNT_DATA}:/data"
      - "./config.yaml:/opt/app/config.yaml"

  client:
    image: szurubooru/client:2.5
    depends_on:
      - server
    environment:
      BACKEND_HOST: server
      BASE_URL:
    volumes:
      - "${MOUNT_DATA}:/data:ro"
    ports:
      - "${PORT}:80"

  sql:
    image: postgres:11-alpine
    restart: unless-stopped
    environment:
      POSTGRES_USER:
      POSTGRES_PASSWORD:
    volumes:
      - "${MOUNT_SQL}:/var/lib/postgresql/data"

六、访问Szurubooru服务

6.1 访问Szurubooru初始页

访问地址：http://192.168.3.88:8080，将IP替换为自己服务器IP地址。如果无法访问到以下页面，则检查宿主机的防火墙是否关闭或者放行相关端口，云服务器则还需要设置安全组规则。

6.2 注册账号

入下图所示，在菜单栏点击“Register ”选项，注册账号。

自定义填写账号相关信息，确认注册即可。

6.3 上传图片

• 上传本地图片

• 预览图片效果

七、总结

在本次Docker项目实战中，我们成功运用Docker容器化技术部署了Szurubooru图像板应用，不仅实现了快速搭建和环境隔离，还显著提升了工作效率。通过Docker进行部署极大缩短了准备时间，同时保证了Szurubooru能够在多种环境中稳定运行。这一过程简化了应用的配置与管理，为开发者提供了极大的便利。鉴于其简便性和实用性，推荐对图像板感兴趣的朋友尝试使用Docker来部署Szurubooru。
