Non-Standard Install use

如果没有从根目录提供Elasticsearch --input-index, --output-index则需要它。如果未提供它们,则将解析附加子目录的索引和类型。

# Copy a single index from a elasticsearch:
elasticdump \
  --input=http://es.com:9200/api/search \
  --input-index=my_index \
  --output=http://es.com:9200/api/search \
  --output-index=my_index \
  --type=mapping

# Copy a single type:
elasticdump \
  --input=http://es.com:9200/api/search \
  --input-index=my_index/my_type \
  --output=http://es.com:9200/api/search \
  --output-index=my_index \
  --type=mapping

# Copy a single type:
elasticdump \
  --input=http://es.com:9200/api/search \
  --input-index=my_index/my_type \
  --output=http://es.com:9200/api/search \
  --output-index=my_index \
  --type=mapping

Docker use

# Copy an index from production to staging with mappings:
docker run --rm -ti taskrabbit/elasticsearch-dump \
  --input=http://production.es.com:9200/my_index \
  --output=http://staging.es.com:9200/my_index \
  --type=mapping
docker run --rm -ti taskrabbit/elasticsearch-dump \
  --input=http://production.es.com:9200/my_index \
  --output=http://staging.es.com:9200/my_index \
  --type=data

# Backup index data to a file:
docker run --rm -ti -v /data:/tmp taskrabbit/elasticsearch-dump \
  --input=http://production.es.com:9200/my_index \
  --output=/tmp/my_index_mapping.json \
  --type=data

如果你需要localhost作为Es主机运行:

docker run --net=host --rm -ti taskrabbit/elasticsearch-dump \
  --input=http://staging.es.com:9200/my_index \
  --output=http://localhost:9200/my_index \
  --type=data

Dump Format

此工具生成的文件格式是以行分隔的JSON文件。转储文件本身不是有效的JSON,但每行都是。我们这样做是为了使转储文件可以流式传输和追加,而不必担心整个文件解析器的整合。

例如,如果要解析每一行,可以执行以下操作:

while read LINE; do jsonlint-py "${LINE}" ; done < dump.data.json
