根据容器ID查询容器进程在宿主机层面的进程

根据容器ID查询容器进程在宿主机层面的进程

1、方法一：

[root@10.66.210.12~]$docker top 6b3396d2bc7b
UID                 PID                 PPID                C                   STIME               TTY                 TIME                CMD
root                2953                2932                0                   11:10               ?                   00:00:00            /sbin/tini -- java -javaagent:/testtools/sandbox/sandbox/lib/sandbox-agent.jar=server.port=7001,server.ip=0.0.0.0 -javaagent:/testtools/test/jacocoagent.jar=output=tcpserver,port=7000,address=0.0.0.0,includes=com.* -Djava.security.egd=file:/dev/./urandom -XX:+UseContainerSupport -XX:MaxRAMPercentage=75.0 -Xss256k -Dapp.name=fund -jar /app.jar --log=json
root                3003                2953                3                   11:10               ?                   00:04:25            java -javaagent:/testtools/sandbox/sandbox/lib/sandbox-agent.jar=server.port=7001,server.ip=0.0.0.0 -javaagent:/testtools/test/jacocoagent.jar=output=tcpserver,port=7000,address=0.0.0.0,includes=com.* -Djava.security.egd=file:/dev/./urandom -XX:+UseContainerSupport -XX:MaxRAMPercentage=75.0 -Xss256k -Dapp.name=fund -jar /app.jar --log=json

2、方法二：

# 根据容器ID查询，查出2932
