脚本宝典收集整理的这篇文章主要介绍了elasticsearch-dump导入导出elasticsearch数据，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。
elasticseArch-dump可以将es中索引的数据、mapping、setting等导出为json格式的文件，或者将相应的文件导入到其他索引中，使用比较灵活。本文将简单介绍docker环境下elasticsearch-dump的操作。
docker pull taskrabbIT/elasticsearch-dump
docker run --rm -ti -v /tmp/data:/tmp taskrabbit/elasticsearch-dump --input=http://es_address:9200/my_index --output=/tmp/index_data.JSON --tyPE=data
执行完毕将在/tmp/data/目录下生成index_data.json文件
docker run --rm -ti -v /tmp/data:/tmp taskrabbit/elasticsearch-dump --input=http://es_address:9200/my_index --output=/tmp/index_mapping.json --type=mapping
执行完毕将在/tmp/data/目录下生成index_mapping.json文件
docker run --rm -ti -v /tmp/data:/tmp taskrabbit/elasticsearch-dump --output=http://es_address:9200/my_index --input=/tmp/index_data.json --type=data
docker run --rm -ti -v /tmp/data:/tmp taskrabbit/elasticsearch-dump --output=http://es_address:9200/my_index --input=/tmp/index_mapping.json --type=mapping

elasticdump: Import and export tools for elasticsearch
version: %%version%%
usage: elasticdump --input SOURCE --output DESTINATION [OPTIONS]
--input
Source location (required)
--input-index
Source index and type
(default: all, example: index/type)
--output
Destination location (required)
--output-index
Destination index and type
(default: all, example: index/type)
--overwrite
Overwrite output file if it exists
(default: false)
--limit
How many objects to move in batch per operation
limit is apPRoxiMATE for file streams
(default: 100)
--size
How many objects to retrieve
(default: -1 -> no limit)
--concurrency
The maximum number of requests the can be made concurrently to a specified transport.
(default: 1)
--concurrencyInterval
The length of time in milliseconds in which up to <intervalCap> requests can be made
before the interval request count resets. Must be finite.
(default: 5000)
--intervalCap
The maximum number of transport requests that can be made within a given <concurrencyInterval>.
(default: 5)
--carryoverConcurrencyCount
If true, any incomplete requests From a <concurrencyInterval> will be carried over to
the next interval, effectively reducing the number of new requests that can be created
in that next interval. If false, up to <intervalCap> requests can be created in the
next interval regardless of the number of incomplete requests from the previous interval.
(default: true)
--throTTLeinterval
Delay in milliseconds between getting data from an inputTransport and sending it to an
outputTransport.
(default: 1)
--debug
Display the elasticsearch commands being used
(default: false)
--quiet
SupPress all messages except for errors
(default: false)
--type
What are we exporting?
(default: data, options: [settings, analyzer, data, mapping, alias, template])
--delete
Delete Documents one-by-one from the input as they are
moved. Will not delete the source index
(default: false)
--searchBody
Preform a partial extract based on search results
when ES is the input, default values are
if ES > 5
`'{"query": { "match_all": {} }, "Stored_fields": ["*"], "_source": true }'`
else
`'{"query": { "match_all": {} }, "fields": ["*"], "_source": true }'`
--headers
Add custom headers to Elastisearch requests (helpful when
your Elasticsearch instance sits behind a Proxy)
(default: '{"User-Agent": "elasticdump"}')
--params
Add custom parameters to Elastisearch requests uri. Helpful when you for example
want to use elasticsearch preference
(default: null)
--sourceOnly
Output only the json contained within the document _source
Normal: {"_index":"","_type":"","_id":"", "_source":{SOURCE}}
sourceOnly: {SOURCE}
(default: false)
--ignore-errors
Will continue the read/write loop on write error
(default: false)
--scrollTime
Time the nodes will hold the requested search in order.
(default: 10m)
--maxSockets
How many simultaneous HTTP requests can we process make?
(default:
5 [node <= v0.10.x] /
Infinity [node >= v0.11.x] )
--timeout
Integer containing the number of milliseconds to wait for
a request to respond before aborting the request. Passed
directly to the request library. Mostly used when you don't
care too much if you lose some data when importing
but rather have speed.
--offset
Integer containing the number of rows you wish to skip
ahead from the input transport. When importing a l@R_304_2604@e
index, things can go wrong, be it connectivity, crashes,
someone forgetting to `screen`, etc. This allows you
to start the dump again from the last known line written
(as LOGged by the `offset` in the output). Please be
advised that since no sorting is specified when the
dump is initially created, there's no real way to
guarantee that the skipped rows have already been
written/parsed. This is more of an option for when
you want to get most data as possible in the index
without concern for losing some rows in the process,
similar to the `timeout` option.
(default: 0)
--noRefresh
Disable input index refresh.
Positive:
1. Much increase index speed
2. Much less hardware requirements
Negative:
1. Recently added data may not be indexed
Recommended to use with Big data indexing,
where speed and System health in a higher priority
than recently added data.
--inputTransport
Provide a custom js file to use as the input transport
--outputTransport
Provide a custom js file to use as the output transport
--toLog
When using a custom outputTransport, should log lines
be appended to the output stream?
(default: true, except for `$`)
--transform
A javascript, which will be called to modify documents
before writing it to destination. global VARiable 'doc'
is available.
Example script for computing a new field 'f2' as doubled
value of field 'F1':
doc._source["f2"] = doc._source.f1 * 2;
May be used multiple times.
Additionally, transform may be performed by a module. See [Module Transform](#module-transform) below.
--awsChain
Use [standard](https://aws.amazon.com/blogs/security/a-new-and-standardized-way-to-manage-credentials-in-the-aws-sdks/) location and ordering for resolving credentials including environment variables, config files, EC2 and ECS metadata locations
_Recommended option for use with AWS_
--awsAccessKeyId
--awsSecretAccessKey
When using Amazon Elasticsearch Service protected by
AWS Identity and Access Management (IAM), provide
your Access Key ID and Secret Access Key.
--sessionToken can also be optionally provided if using temporary credentials
--awsIniFileProfile
Alternative to --awsAccessKeyId and --awsSecretAccessKey,
loads credentials from a specified profile in aws ini file.
For greater flexibility, consider using --awsChain
and setting AWS_PROFILE and AWS_CONFIG_FILE
environment variables to override defaults if needed
--awsIniFileName
Override the default aws ini file name when using --awsIniFileProfile
Filename is relative to ~/.aws/
(default: config)
--support-big-int
Support big integer numbers
--retryAttempts
Integer indicating the number of times a request should be automatically re-attempted before failing
when a connection fails with one of the following errors `ECONNRESET`, `ENOTFOUND`, `ESOCKETTIMEDOUT`,
ETIMEDOUT`, `ECONNREFUSED`, `EHOSTUNReach`, `EPIPE`, `EAI_AGAIN`
(default: 0)
--retryDelay
Integer indicating the back-off/break period between retry attempts (milliseconds)
(default : 5000)
--parseExtraFields
Comma-separated list of meta-fields to be parsed
--fileSize
supports file splitting. This value must be a string supported by the **bytes** module.
The following abbreviations must be used to signify size in terms of units
b for bytes
kb for kilobytes
mb for megabytes
gb for gigabytes
tb for terabytes
e.g. 10mb / 1gb / 1tb
Partitioning helps to alleviate overflow/out of memory exceptions by efficiently segmenting files
into smaller chunks that then be merged if needs be.
--fsCompress
gzip data before sending outputting to file
--s3AccessKeyId
AWS access key ID
--s3SecretAccessKey
AWS secret access key
--s3Region

--s3Compress

Activate custom customBackoff function. (s3)
--tlsAuth
Enable TLS X509 client authentication
--cert, --input-cert, --output-cert
Client certificate file. Use --cert if source and destination are identical.
Otherwise, use the one prefixed with --input or --output as needed.
--key, --input-key, --output-key
Private key file. Use --key if source and destination are identical.
Otherwise, use the one prefixed with --input or --output as needed.
