Docker cannot start Elasticsearch
If you run Elasticsearch in docker, you’ll probably run into the same issue as mine
ERROR: [1] bootstrap checks failed
elasticsearch_1 | [1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
To fix this, just run the following command:
sudo sysctl -w vm.max_map_count=262144
Run Elastic and Kibana using Docker
Docker engine and docker compose is the fastest way to try out Elastic and Kibana together
# Need to change this setup, otherwise elastic will fail and exit with code 78 sudo sysctl -w vm.max_map_count=262144
Create a docker-compose.yml file in any folder

Install docker and docker-compose on Linux
The following commands help you install both docker and docker-compose at the same time, and also setup for the current user to run docker properly:
sudo apt-get remove docker docker-engine docker.io containerd runc
sudo apt-get update
sudo apt-get install \
apt-transport-https \
ca-certificates \
curl \
gnupg-agent \
software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io
sudo usermod -aG docker $USER
docker run hello-world
sudo systemctl enable docker
sudo curl -L "https://github.com/docker/compose/releases/download/1.27.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
Run MySQL using Docker
docker pull mysql/mysql-server docker images docker run --name=mysql1 --restart on-failure -d mysql/mysql-server:latest docker logs mysql1 docker logs mysql1 2>&1 | grep GENERATED GENERATED ROOT PASSWORD: Axegh3kAJyDLaRuBemecis&EShOs docker exec -it mysql1 mysql -uroot -p docker stop mysql1 docker restart mysql1 docker rm mysql1
You can get mysql password in docker using the log command as above
