+In this post, I will cover how you can set up Elasticsearch and Kibana with a single `docker-compose.yml` file.
+
+## Set up and install ELK stack on Ubuntu server
+
+You must run `sudo sysctl -w vm.max_map_count=262144` to get Elasticsearch to work. To make this permanent, run `sudo nano /etc/sysctl.conf` and add `vm.max_map_count=262144` to the end of the file on a new line, then save and exit.
+
+Go to the directory with the files in. Make sure you've used SFTP to put the `docker-compose.yml` file in there first. For example you may need to use this command `cd /home/administrator/docker/elk-stack`
+
+Install it all with `docker-compose up -d` and you're finished! It really is that simple.
+
+The compose file is as below.
+
+```docker
+version: '2.2'
+
+services:
+
+  elasticsearch:
+    image: docker.elastic.co/elasticsearch/elasticsearch:7.9.3
+    container_name: elasticsearch

+    environment:
+      ELASTICSEARCH_URL: "http://elasticsearch:9200"
+      ELASTICSEARCH_SHARDTIMEOUT: 300000
+    ports:
