Arkime Docker image/container

This repository contains the files to build a Docker image of the Arkime software:

https://arkime.com/

Ready to use Docker images can be pulled from https://hub.docker.com/r/mammo0/docker-arkime

To run this image a working Elasticsearch environment is required. Please stick to their documentation for setting this up. (E.g. for docker: https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html)

Run the container

This image can be run with

docker run \
    -e ES_HOST=elasticsearch \
    -e ES_PORT 9200 \
    -v <config_volume>:/data/config \
    -v <pcap_volume>:/data/pcap \
    -v <log_volume>:/data/logs \
    mammo0/docker-arkime:<tag>

These parameters are available:

ENV VARIABLE	DEFAULT VALUE	NOTES
ES_HOST	elasticsearch	The hostname or IP address where Elasticsearch is running.
ES_PORT	9200	The port where Elasticsearch is reachable.
ARKIME_ADMIN_PASSWORD	admin	This is the password for the Arkime admin user that is needed for the first login. It can be changed afterwards.
ARKIME_INTERFACE	eth0	Network interface where capture process listens. This feature is not tested yet!
ARKIME_HOSTNAME	localhost	With this hostname Arkime authenticates at Elasticsearch. So if you change this you'll lose your Elasticsearch configuration.
CAPTURE	off	Set to "on" to activate the capture process. This feature is not tested yet!
VIEWER	on	Set to "off" to deactivate the Arkime viewer.

VOLUME	CONTAINER PATH	NOTES
config_volume	/data/config	In this directory the Arkime configuration is saved.
pcap_volume	/data/pcap	In this directory the pcap files are saved that are generated by capture.
log_volume	/data/logs	In this directory the Arkime log files are saved.

Use docker-compose

You can use docker-compose if you want to setup Elasticsearch together with Arkime in one step.

Configuration

1. Please copy or rename the file docker-compose.env to .env before running docker-compose up. You may want to change some of the variables inside. Each variable is documented there.

2. Please ensure you have done this step (otherwise Elasticsearch won't start): https://www.elastic.co/guide/en/elasticsearch/reference/current/vm-max-map-count.html

3. Run chmod -R 777 es_data OR chown -R 1000:1000 es_data. This is needed for the Elasticsearch containers to be able to write to that direcotry.

Start

Simply run

docker-compose up -d

It can take some time until the Elasticsearch instances are fully started.

The Arkime viewer instance can be accessed via

http://localhost:8005

Assuming you don't changed the default port in the .env file.

Import pcap files

To import existing pcap files have a look at scripts/arkime-parse-pcap-folder.sh script. It can be run within the running container:

docker exec -it <container_name> \
    /data/arkime-parse-pcap-folder.sh -d <directory_with_pcap_files> -t <tag>

If parameter -d is omitted, the script asks if you want to import the default direcotry /data/pcap.
