Cara Instalasi ELK Stack menggunakan Docker Compose – Mungkin sudah banyak ya artikel bersebaran membahas bagaimana instalasi ELK Stack. Kali ini admin juga ingin membahas langkah-langkah instalasi ELK Stack tersebut.
Artikel ini menurutku akan lebih mudah untuk dicoba, dibanding kalau kita intalasi komponenya satu per-satu. Namun, untuk yang ingin mendalami atau memahami komponen-komponenya saya sarankan untuk mencoba instalasi secara manual.
Hal-hal yang perlu dipersiapkan:
- Linux Server
- Docker
- Docker Compose
Baca spesifikasi hardware yang perlu dipersiapkan untuk membuat ELK Stack.
Jika sudah anda persiapkan, silahkan membuat folder terserah dimana.
mkdir ~/elk
cd ~/elkBuat file .env untuk keperluan docker-compose.yml:
# Password for the 'elastic' user (at least 6 characters) ELASTIC_PASSWORD=elasticpassword2022 # Password for the 'kibana_system' user (at least 6 characters) KIBANA_PASSWORD=kibanapassword2022 # Version of Elastic products STACK_VERSION=7.13.4 # Set the cluster name CLUSTER_NAME=elk-cluster # Set to 'basic' or 'trial' to automatically start the 30-day trial LICENSE=basic #LICENSE=trial # Port to expose Elasticsearch HTTP API to the host ES_PORT=9200 #ES_PORT=127.0.0.1:9200 # Port to expose Kibana to the host KIBANA_PORT=5601 #KIBANA_PORT=80 # Increase or decrease based on the available host memory (in bytes) MEM_LIMIT=3221225472 # Project namespace (defaults to the current folder name if not set) #COMPOSE_PROJECT_NAME=myproject
Persiapkan file docker-compose.yml dan isi dengan konten berikut:
vi docker-compose.ymlversion: "2.2"

setup:

volumes:
- certs:/usr/share/elasticsearch/config/certs

bash -c '
if [ x${ELASTIC_PASSWORD} == x ]; then
echo "Set the ELASTIC_PASSWORD environment variable in the .env file";
exit 1;
elif [ x${KIBANA_PASSWORD} == x ]; then
echo "Set the KIBANA_PASSWORD environment variable in the .env file";
exit 1;
fi;
if [ ! -f config/certs/ca.zip ]; then
echo "Creating CA";

unzip config/certs/certs.zip -d config/certs;
fi;
echo "Setting file permissions"
chown -R root:root config/certs;
find . -type d -exec chmod 750 \{\} \;;

echo "Waiting for Elasticsearch availability";
until curl -s --cacert config/certs/ca/ca.crt https://es01:9200 | grep -q "missing authentication credentials"; do sleep 30; done;
echo "Setting kibana_system password";
until curl -s -X POST --cacert config/certs/ca/ca.crt -u elastic:${ELASTIC_PASSWORD} -H "Content-Type: application/json" https://es01:9200/_security/user/kibana_system/_password -d "{\"password\":\"${KIBANA_PASSWORD}\"}" | grep -q "^{}"; do sleep 10; done;

Jalankan Docker Compose untuk membuat container ELK Stack:
docker-compose up -dJika ELK berhasil running tampilanya seperti ini:
Agar ELK Stack dapat diakses, jangan lupa buka port yang digunakan oleh ELK. Seperti elasticsearch port 9200, kibana port 5601. Jangan lupa port 80 dan 443 juga anda open.
Silahkan coba akses dashboard Kibana: IP_ADDRESS:5601
Untuk integrasi host client (sebagai agent) ke ELK Stack akan ditulis diartikel lain. Terimakasih
