这里使用 swoole 官方的镜像：https://github.com/swoole/doc...
版本说明：
- latest：使用的是最新版本的PHP和Swoole的master分支
- php7.x：使用的是7.x版本的PHP和Swoole的master分支
- 4.x.x-php7.x：使用的是7.x.xx版本的PHP和Swoole的4.x.x分支
安装测试：
拉取指定版本的镜像：
docker pull phpswoole/swoole:4.5.9-php7.4测试镜像环境：
docker run --rm phpswoole/swoole:4.5.9-php7.4 "php -m"
docker run --rm phpswoole/swoole:4.5.9-php7.4 "php --ri swoole"
docker run --rm phpswoole/swoole:4.5.9-php7.4 "composer --version"基本使用：
创建HTTP服务器端：
# /d/swoole/www/server.php
#!/usr/bin/env php
on(
"request",
function (Swoole\Http\Request $request, Swoole\Http\Response $response) {
$response->end(
<<start(); 启动容器：
docker run --rm -p 8000:9501 --name swoole -v /d/swoole/www:/var/www phpswoole/swoole:4.5.9-php7.4测试访问：
curl http://127.0.0.1:8000容器启动后会尝试执行 php server.php 命令启动服务，所以无需手动进入容器执行。
使用 docker-compose 自动重启服务
创建 docker-compose.yml 文件：
# This docker-compose.yml file shows how Supervisor program(s) are reloaded automatically when file changes detected
# under web root /var/www. There are two environment variables used:
# 1. AUTORELOAD_PROGRAMS: space-separated Supervisor program(s) to be reloaded when file changes detected. e.g.,
# AUTORELOAD_PROGRAMS: "swoole" # Autoreload Supervisor program "swoole" only.
# AUTORELOAD_PROGRAMS: "swoole nginx" # Autoreload Supervisor program "swoole" and "nginx".
# 2. AUTORELOAD_ANY_FILES: Optional. If set to "true", "1", "yes", or "y", reload Supervisor program(s) when any
# files under the root directory (/var/www in this example) is changed; otherwise, reload only when PHP file(s)
# are changed.
#
version: '3'
services:
app:
build: .
environment:
AUTORELOAD_PROGRAMS: "swoole"
AUTORELOAD_ANY_FILES: 0
ports:
- 8000:9501
volumes:
- ./www:/var/www同目录下创建 Dockerfile 文件：
FROM phpswoole/swoole:4.5.9-php7.4
# COPY ./www/ /var/www/构建并启动容器：
docker-compose -f "docker-compose.yml" up --build --force-recreate -d
docker-compose -f "docker-compose.yml" stopdocker-compose 参数说明：
-f, –file FILE 指定Compose模板文件，默认为docker-compose.ymldocker-compose up 参数说明：
-–build 在启动容器前构建服务镜像
–force-recreate 强制重新创建容器，不能与–no-recreate同时使用
-d 在后台运行服务容器并打印名称自动执行 php server.php 探究
官方镜像的 Dockerfile 中，构建完成后会执行以下内容：
# dockerfiles\4.5.9\php7.4\cli\Dockerfile
ENTRYPOINT ["/entrypoint.sh"]
CMD []
WORKDIR "/var/www/"然后会去扫描 usr/local/boot/ 目录下的脚本并执行：
# rootfilesystem\entrypoint.sh
# Now run .php and .sh scripts under folder /usr/local/boot in order.
boot_scripts=()
shopt -s nullglob
for f in /usr/local/boot/*.sh ; do
boot_scripts+=("$f")
done
shopt -u nullglob
IFS=$'\n' boot_scripts=($(sort <<<"${boot_scripts[*]}"))
unset IFS
for f in "${boot_scripts[@]}" ; do
. "$f"
done然后会去扫描 etc/supervisor/service.d/ 目录下的配置并执行：
# usr\local\boot\supervisor.sh
case "${BOOT_MODE}" in
"SERVICE")
echo "INFO: Supervisord configuration files copied from folder '/etc/supervisor/${BOOT_MODE,,}.d/'."
find /etc/supervisor/${BOOT_MODE,,}.d/ -mindepth 1 -type f -name "*.conf" -exec cp -t /etc/supervisor/conf.d/ {} +
;;在配置中执行了执行的命令为 php /var/www/server.php
