# Get health information from your running containers > Get health information from your running Docker containers instantly. This article shows a bash script using docker ps and docker inspect for quick checks. ---  **TL;DR** This article shares a Bash script that loops over all Docker containers (`docker container list --all`) and reports each one's health status via `docker inspect`'s `State.Health` field, giving a quick overview of which containers are healthy, unhealthy, or have no healthcheck configured (`null`). When you've a few runnings containers on your machine, you can quickly retrieve the health information using `docker ps` and its `State.Health` response. In this article, we'll look at how to create a bash script that can be used as a basis for other needs. ## The one-glance overview Here is what I get on my machine, in one command:  I've a few containers running, a lot are `healthy` meaning that they're running and without any issue, I've two containers in a `null` state i.e. they are sleeping and none are stopped due to an error. That's the whole point: one screen, and you know which container needs your attention. ## The script that produces it Please create somewhere on your disk, in a Linux console, a script f.i. called `health.sh` with this content: **health.sh** ```bash #!/usr/bin/env bash # Intentionally no "errexit": one container's failed inspect shouldn't stop the # whole list from being checked. set -o nounset -o pipefail GRAY=30 GREEN=32 RED=31 clear printf "\e[1;33m%s\e[0m\n\n" "Docker containers - Health check" docker container list --all --format "{{.Names}}" | while read -r name; do healthcheckStatus=$(docker inspect --format='{{json .State.Health}}' "$name" | jq -r '.Status') # Default color COLOR=${GRAY} if [[ "$healthcheckStatus" == "healthy" ]]; then COLOR=${GREEN} elif [[ ! "$healthcheckStatus" == "null" ]]; then COLOR=${RED} fi printf "%-40s\e[1;${COLOR}m%s\e[0m\n" "$name" "$healthcheckStatus" done ``` Make sure to make the script executable: `chmod +x health.sh`, then run it with `./health.sh`. > **Get the list of all containers:** > > `docker container list --all --format "{{.Names}}"` return the list of all containers and only echo the column `Name` on the console. ## Conclusion A few lines of Bash, and the question *"is everything still fine on this machine?"* gets an answer in one look instead of a `docker inspect` per container. Don't hesitate to fine-tune the script to fit your needs. This script gives you a snapshot, on demand. If you'd rather be **notified** when a service goes down, have a look at [Self-hosted monitoring tool](/blog/docker_uptime_kuma). And when a container is up but still unreachable from another one, [Troubleshooting for Docker containers - Accessing the other one](/blog/docker-networking-troubleshooting) walks through the diagnosis, layer by layer.
