答复: mesos-logrotate-logger binary package problem？

[pangbingqiang]

Thank you for your replay. In "parameters" option the             
            {
                "key": "logrotate_stdout_options",
                "value": "rotate 7\nmissingok\ncompress\ndelaycompress"
            },
The system call logrotate must set a option "create" or "copytruncate", which 
mode mesos set ?
If choose "copytruncate" mode, it may be lost some log?

That program is not meant to be executed manually. Instead you should configure 
the logger in the modules flags of your mesos slave.

Here is a snippets of a script I used when testing the logrotate logger, you 
can adjust for your own use case:

MODULES_JSON_FILE=/tmp/modules.json
cat >$MODULES_JSON_FILE<<EOF
{
    "libraries": [
    {
        "file":
"${MESOS_BUILD_DIR}/src/.libs/liblogrotate_container_logger.so",
        "modules": [
        {
            "name": "org_apache_mesos_LogrotateContainerLogger",
            "parameters": [
            {
                "key": "launcher_dir",
                "value": "${MESOS_BUILD_DIR}/src/"
            },
            {
                "key": "max_stdout_size",
                "value": "4096B"
            },
            {
                "key": "max_stderr_size",
                "value": "4096B"
            },
            {
                "key": "logrotate_stdout_options",
                "value": "rotate 7\nmissingok\ncompress\ndelaycompress"
            },
            {
                "key": "logrotate_stderr_options",
                "value": "rotate 7\nmissingok\ncompress\ndelaycompress"
            }
            ]
        }
        ]
    }
    ]
}
EOF
