Maintain crontab files for individual users.

Edit the current crontab. After exiting the editor, the modified crontab will be installed automatically.

crontab -e

Display the current crontab on standard output

crontab -l

Start a Docker project when host system is rebooted

@reboot sleep 60 && touch /home/chris/docker-project/reboot.log && echo "$(date): System rebooted, attempting to start." >> /home/chris/docker-project/reboot.log && cd /home/chris/docker-project && docker compose up -d

Save output to file

*   *   *   *   *   /home/chris/ > /bin/purge.log 2>&1

Build and tag an image from a Dockerfile in the same directory

docker build -t node-demo .

Start a container

docker run -i -t ubuntu /bin/bash
docker run -it node:19 /bin/bash
docker run -it --rm -d -p 8080:80 --name web nginx

Docker compose

docker-compose up --build
docker-compose up --remove-orphans -d

Stop all containers

docker stop $(docker ps -aq)

Remove all containers

docker rm $(docker ps -aq)

List images

docker images

See which containers are running

docker ps

See all containers, including non-running

docker ps -a

Remove stopped containers and images, including unused and dangling images

docker system prune -a

Delete all images

sudo docker rmi $(sudo docker images -q) --force

Run a php script inside a container

docker run --rm -v $(pwd):/app -w /app php:cli php hello.php

Get ip address of container

docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' <container name>
sudo docker inspect <container name> | grep IPAddress

Command prompt into a container

sudo docker exec -it  bash
sudo docker exec -it wp-local-docker_phpfpm_1 /bin/sh -c "[ -e /bin/bash ] && /bin/bash || /bin/sh"
docker-compose exec --user www-data phpfpm bash

Keep a container running. From docker-compose.yml

    command: bash -c "while true; do echo 'sleeping...' && sleep 10; done"

phpMyAdmin in Docker

Updated: 16 November 2023

phpMyAdmin is available as a Docker image. The MySQL server connection parameters are provided when the container is instantiated.

For a remote MySQL server

docker run --name myadmin \
-e PMA_HOST= \
-e PMA_PORT=3306 \
-e PMA_USER=user \
-e PMA_PASSWORD=password \
-p 8080:80 \

Browse to phpMyAdmin at http://localhost:8080

MySQL server running in a local Docker network some-network

docker run --name myadmin \
--network=some-network \
-e PMA_HOST=db \
-e PMA_PORT=3306 \
-p 8080:80 \

--network The docker network the phpMyAdmin container will join.
