basic local setup for testing ELK stack

Naive Setup

Elastic Search

Create a common network so that other services can connect to Elastic Search. eg: Kibana

docker network create elastic-search-network

Make sure you have elastic search image (elastic search doesn't have latest tag)

docker pull elasticsearch:8.1.2

Start Elasticsearch container

docker run -d --name elasticsearch --net elastic-search-network -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:8.1.2

Setting up passwords

Since the log might not be visible for us in detach mode the elastic seach is not auto generating passwords.

For setting up all the passwords manually.

docker exec -it elasticsearch ./bin/elasticsearch-setup-passwords interactive

For generating random passwords

docker exec -it elasticsearch ./bin/elasticsearch-setup-passwords auto

Verify the connection

For checking if you are able to access the elasticseach container

curl -u elastic:password https://localhost:9200 -k

here, -k means insecure via https, elastic (there are other users as well) is the username password is the password set in previous step.

or

Find certificate location

docker exec -it elasticsearch /bin/bash -c "find /usr/share/elasticsearch -name http_ca.crt"

copy it to the host system

docker cp elasticsearch:/usr/share/elasticsearch/config/certs/http_ca.crt .

and then curl

curl --cacert http_ca.crt -u elastic https://localhost:9200

Generating enrollment token for connecting with kibana

docker exec elasticsearch ./bin/elasticsearch-create-enrollment-token --scope kibana

Kibana

Make sure you have kibana image (same as elastic search doesn't have latest tag)

docker pull kibana:8.1.2

Create kibana on same network as elastic search container

docker run -d --name kibana --net elastic-search-network -p 5601:5601 kibana:8.1.2

Verification code

Once you verity Kibana with token. You will be asked for verification code. You can get verification code using.

docker exec kibana ./bin/kibana-verification-code
