elasticsearch-nextcloud-docker

A docker container hosting elasticsearch with ingest-attachment plugin enabled (compatible with NC fulltext search)

How to use this

Basically all you have to do is to copy the docker-compose.yml file, create a .env file with the desired Elasticsearch version and then run docker-compose up. Of course you could also just clone this repository and apply changes to your need.

Example:

wget https://raw.githubusercontent.com/R0Wi/elasticsearch-nextcloud-docker/master/docker-compose.yml
echo "DOCKER_TAG=8.6.1" > .env
docker-compose up -d

Alternatively you can also use the docker run command:

docker run -d \
    -v elastic_data:/usr/share/elasticsearch/data \
    -p 127.0.0.1:9200:9200 \
    -e "cluster.name=docker-cluster" \
    -e "bootstrap.memory_lock=true" \
    -e "ES_JAVA_OPTS=-Xms512m -Xmx512m" \
    -e "discovery.type=single-node" \
    -e "xpack.security.enabled=false" \
    --restart always \
    r0wi/elasticsearch-nextcloud-docker:8.6.1

Authentication

To setup Basic Authentication for the built-in user elastic, adjust the environment variables as follows:

    environment:
      - cluster.name=docker-cluster
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - discovery.type=single-node
      - xpack.security.enabled=true
      - xpack.security.http.ssl.enabled=false
      - ELASTIC_PASSWORD=mySuperSecret

To authenticate against your ES instance, you could for example embed the credentials into your url like this: http://elastic:mySuperSecret@localhost:9200/myindex. See https://www.elastic.co/guide/en/elasticsearch/reference/current/security-minimal-setup.html for more details.

Versioninig

The tags in this repository will also be available on docker hub. They correspond to the elasticsearch versions.

If there is a version missing which you might need please create a new issue. You can find all available Elasticsearch versions for docker here.

Log4j CVE-2021-44228

Please note: the "unofficial" version 7.6.1 already contains the patch for log4j patch, mentioned at https://nvd.nist.gov/vuln/detail/CVE-2021-44228, which is basically the same as the official one applied by the Elasticsearch community (https://github.com/elastic/elasticsearch/commit/5b38441b16b1ebb16a27c107a4c3865776e20c53). It strips out the JndiLookup-class from log4j-core.jar. Since the official patch is only available for ES v7.16.1 and v6.8.21, this repository backports the patch to the older version 7.6.1, too. For further details have a look at the Dockerfile.
