#mesos-slave命令介绍 Usage: mesos-slave [...]
Supported options: --attributes=VALUE Attributes of machine, in the form: rack:2 or 'rack:2;u:1' --authenticatee=VALUE Authenticatee implementation to use when authenticating against the master. Use the default 'crammd5', or load an alternate authenticatee module using --modules. (default: crammd5) --[no-]cgroups_enable_cfs Cgroups feature flag to enable hard limits on CPU resources via the CFS bandwidth limiting subfeature. (default: false) --cgroups_hierarchy=VALUE The path to the cgroups hierarchy root (default: /sys/fs/cgroup) --[no-]cgroups_limit_swap Cgroups feature flag to enable memory limits on both memory and swap instead of just memory. (default: false) --cgroups_root=VALUE Name of the root cgroup (default: mesos) --container_disk_watch_interval=VALUE The interval between disk quota checks for containers. This flag is used for the 'posix/disk' isolator. (default: 15secs) --containerizer_path=VALUE The path to the external containerizer executable used when external isolation is activated (--isolation=external).
--containerizers=VALUE Comma separated list of containerizer implementations to compose in order to provide containerization. Available options are 'mesos', 'external', and 'docker' (on Linux). The order the containerizers are specified is the order they are tried (--containerizers=mesos). (default: mesos) --credential=VALUE Either a path to a text with a single line containing 'principal' and 'secret' separated by whitespace. Or a path containing the JSON formatted information used for one credential. Path could be of the form 'file:///path/to/file' or '/path/to/file'. Example: { "principal": "username", "secret": "secret", } --default_container_image=VALUE The default container image to use if not specified by a task, when using external containerizer.
--default_container_info=VALUE JSON formatted ContainerInfo that will be included into any ExecutorInfo that does not specify a ContainerInfo.
See the ContainerInfo protobuf in mesos.proto for
the expected format.
Example:
{
"type": "MESOS",
"volumes": [
{
"host_path": "./.private/tmp",
"container_path": "/tmp",
"mode": "RW"
}
]
}
--default_role=VALUE Any resources in the --resources flag that omit a role, as well as any resources that are not present in --resources but that are automatically detected, will be assigned to this role. (default: *) --disk_watch_interval=VALUE Periodic time interval (e.g., 10secs, 2mins, etc) to check the overall disk usage managed by the slave. This drives the garbage collection of archived information and sandboxes. (default: 1mins) --docker=VALUE The absolute path to the docker executable for docker containerizer. (default: docker) --docker_remove_delay=VALUE The amount of time to wait before removing docker containers (e.g., 3days, 2weeks, etc). (default: 6hrs) --docker_sandbox_directory=VALUE The absolute path for the directory in the container where the sandbox is mapped to. (default: /mnt/mesos/sandbox) --docker_stop_timeout=VALUE The time as a duration for docker to wait after stopping an instance before it kills that instance. (default: 0ns) --[no-]enforce_container_disk_quota Whether to enable disk quota enforcement for containers. This flag is used for the 'posix/disk' isolator. (default: false) --executor_registration_timeout=VALUE Amount of time to wait for an executor to register with the slave before considering it hung and shutting it down (e.g., 60secs, 3mins, etc) (default: 1mins) --executor_shutdown_grace_period=VALUE Amount of time to wait for an executor to shut down (e.g., 60secs, 3mins, etc) (default: 5secs) --external_log_file=VALUE Specified the externally managed log file. This file will be exposed in the webui and HTTP api. This is useful when using stderr logging as the log file is otherwise unknown to Mesos. --frameworks_home=VALUE Directory path prepended to relative executor URIs (default: ) --gc_delay=VALUE Maximum amount of time to wait before cleaning up executor directories (e.g., 3days, 2weeks, etc). Note that this delay may be shorter depending on the available disk usage. (default: 1weeks) --gc_disk_headroom=VALUE Adjust disk headroom used to calculate maximum executor directory age. Age is calculated by: gc_delay * max(0.0, (1.0 - gc_disk_headroom - disk usage)) every --disk_watch_interval duration. gc_disk_headroom must be a value between 0.0 and 1.0 (default: 0.1) --hadoop_home=VALUE Path to find Hadoop installed (for fetching framework executors from HDFS) (no default, look for HADOOP_HOME in environment or find hadoop on PATH) (default: ) --[no-]help Prints this help message (default: false) --hooks=VALUE A comma separated list of hook modules to be installed inside the slave. --hostname=VALUE The hostname the slave should report. If left unset, the hostname is resolved from the IP address that the slave binds to. --[no-]initialize_driver_logging Whether to automatically initialize google logging of scheduler and/or executor drivers. (default: true) --ip=VALUE IP address to listen on --isolation=VALUE Isolation mechanisms to use, e.g., 'posix/cpu,posix/mem', or 'cgroups/cpu,cgroups/mem', or network/port_mapping (configure with flag: --with-network-isolator to enable), or 'external', or load an alternate isolator module using the --modules flag. (default: posix/cpu,posix/mem) --launcher_dir=VALUE Directory path of Mesos binaries (default: /usr/libexec/mesos) --log_dir=VALUE Directory path to put log files (no default, nothing is written to disk unless specified; does not affect logging to stderr). NOTE: 3rd party log messages (e.g. ZooKeeper) are only written to stderr!
--logbufsecs=VALUE How many seconds to buffer log messages for (default: 0) --logging_level=VALUE Log message at or above this level; possible values: 'INFO', 'WARNING', 'ERROR'; if quiet flag is used, this will affect just the logs from log_dir (if specified) (default: INFO) --master=VALUE May be one of: zk://host1:port1,host2:port2,.../path zk://username:password@host1:port1,host2:port2,.../path file:///path/to/file (where file contains one of the above) --modules=VALUE List of modules to be loaded and be available to the internal subsystems.
Use --modules=filepath to specify the list of modules via a
file containing a JSON formatted string. 'filepath' can be
of the form 'file:///path/to/file' or '/path/to/file'.
Use --modules="{...}" to specify the list of modules inline.
Example:
{
"libraries": [
{
"file": "/path/to/libfoo.so",
"modules": [
{
"name": "org_apache_mesos_bar",
"parameters": [
{
"key": "X",
"value": "Y"
}
]
},
{
"name": "org_apache_mesos_baz"
}
]
},
{
"name": "qux",
"modules": [
{
"name": "org_apache_mesos_norf"
}
]
}
]
}
--perf_duration=VALUE Duration of a perf stat sample. The duration must be less that the perf_interval. (default: 10secs) --perf_events=VALUE List of command-separated perf events to sample for each container when using the perf_event isolator. Default is none. Run command 'perf list' to see all events. Event names are sanitized by downcasing and replacing hyphens with underscores when reported in the PerfStatistics protobuf, e.g., cpu-cycles becomes cpu_cycles; see the PerfStatistics protobuf for all names. --perf_interval=VALUE Interval between the start of perf stat samples. Perf samples are obtained periodically according to perf_interval and the most recently obtained sample is returned rather than sampling on demand. For this reason, perf_interval is independent of the resource monitoring interval (default: 1mins) --port=VALUE Port to listen on (default: 5051) --[no-]quiet Disable logging to stderr (default: false) --recover=VALUE Whether to recover status updates and reconnect with old executors. Valid values for 'recover' are reconnect: Reconnect with any old live executors. cleanup : Kill any old live executors and exit. Use this option when doing an incompatible slave or executor upgrade!). NOTE: If checkpointed slave doesn't exist, no recovery is performed and the slave registers with the master as a new slave. (default: reconnect) --recovery_timeout=VALUE Amount of time alloted for the slave to recover. If the slave takes longer than recovery_timeout to recover, any executors that are waiting to reconnect to the slave will self-terminate. NOTE: This flag is only applicable when checkpoint is enabled. (default: 15mins) --registration_backoff_factor=VALUE Slave initially picks a random amount of time between [0, b], where b = registration_backoff_factor, to (re-)register with a new master. Subsequent retries are exponentially backed off based on this interval (e.g., 1st retry uses a random value between [0, b * 2^1], 2nd retry between [0, b * 2^2], 3rd retry between [0, b * 2^3] etc) up to a maximum of 1mins (default: 1secs) --resource_monitoring_interval=VALUE Periodic time interval for monitoring executor resource usage (e.g., 10secs, 1min, etc) (default: 1secs) --resources=VALUE Total consumable resources per slave, in the form 'name(role):value;name(role):value...'. --slave_subsystems=VALUE List of comma-separated cgroup subsystems to run the slave binary in, e.g., 'memory,cpuacct'. The default is none. Present functionality is intended for resource monitoring and no cgroup limits are set, they are inherited from the root mesos cgroup. --[no-]strict If strict=true, any and all recovery errors are considered fatal. If strict=false, any expected errors (e.g., slave cannot recover information about an executor, because the slave died right before the executor registered.) during recovery are ignored and as much state as possible is recovered. (default: true) --[no-]switch_user Whether to run tasks as the user who submitted them rather than the user running the slave (requires setuid permission) (default: true) --[no-]version Show version and exit. (default: false) --work_dir=VALUE Directory path to place framework work directories (default: /tmp/mesos)
