使用iris-main
iris-main是IRIS镜像的的ENTRYPOINT程序。 在Container中，ENTRYPOINT 指令允许你指定一个可执行程序或者脚本，作为容器启动后运行的主程序。这个程序会在容器启动时自动执行。
执行docker ps命令可以看到当前container的ENTRYPOINT是什么：
hma@CNMBP23HMA demo % docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
8f31a857dc90 .../irishealth:2024.2 "/tini -- /iris-main" 3 days ago Up 3 days 2188/tcp, 52773/tcp, 53773/tcp, 54773/tcp, 0.0.0.0:1980->1972/tcp iris-a

我们可以用root进入container, 在根目录下查看iris-main的帮助, 或者查看在线文档的帮助-iris-main。
使用的iris-main例子
以下的compose文件中， 使用了--check-caps false关闭了LInux的能力检查(capability check), 使用--key /install/iris.key加载了IRIS的license文件，并且配置了--after /install/installer.sh,它定义在container启动执行install.sh脚本。
iris-a:
image: containers.intersystems.com/intersystems/irishealth-arm64:2024.2
container_name: iris-a
hostname: irisa
ports:
- 1980:1972
- 52773:52773
environment:
- TZ=CST-8
volumes:
- ./install:/install
command:
--check-caps false
--key /install/iris.key
--after /install/installer.sh
