Docker helps +you get set up quickly, and doesn't install anything permanent on the system, which makes uninstalling the Agent easy. + +See our full list of Docker images at [Docker Hub](https://hub.docker.com/r/netdata/netdata). + +Starting with v1.12, Netdata collects anonymous usage information by default and sends it to Google Analytics. Read +about the information collected, and learn how to-opt, on our [anonymous statistics](/docs/anonymous-statistics.md) +page. + +The usage statistics are _vital_ for us, as we use them to discover bugs and prioritize new features. We thank you for +_actively_ contributing to Netdata's future. + +## Limitations running the Agent in Docker + +For monitoring the whole host, running the Agent in a container can limit its capabilities. Some data, like the host OS +performance or status, is not accessible or not as detailed in a container as when running the Agent directly on the +host. + +A way around this is to provide special mounts to the Docker container so that the Agent can get visibility on host OS +information like `/sys` and `/proc` folders or even `/etc/group` and shadow files. + +Also, we now ship Docker images using an [ENTRYPOINT](https://docs.docker.com/engine/reference/builder/#entrypoint) +directive, not a COMMAND directive. Please adapt your execution scripts accordingly. You can find more information about +ENTRYPOINT vs COMMAND in the [Docker +documentation](https://docs.docker.com/engine/reference/builder/#understand-how-cmd-and-entrypoint-interact). + +## Create a new Netdata Agent container + +You can create a new Agent container using either `docker run` or Docker Compose. After using either method, you can +visit the Agent dashboard `http://NODE:19999`. + +Both methods create a [bind mount](https://docs.docker.com/storage/bind-mounts/) for Netdata's configuration files +_within the container_ at `/etc/netdata`. See the [configuration section](#configure-agent-containers) for details. If +you want to access the configuration files from your _host_ machine, see [host-editable +configuration](#host-editable-configuration). + +**`docker run`**: Use the `docker run` command, along with the following options, to start a new container. + +```bash +docker run -d --name=netdata \ + -p 19999:19999 \ + -v netdataconfig:/etc/netdata \ + -v netdatalib:/var/lib/netdata \ + -v netdatacache:/var/cache/netdata \ + -v /etc/passwd:/host/etc/passwd:ro \ + -v /etc/group:/host/etc/group:ro \ + -v /proc:/host/proc:ro \ + -v /sys:/host/sys:ro \ + -v /etc/os-release:/host/etc/os-release:ro \ + --restart unless-stopped \ + --cap-add SYS_PTRACE \ + --security-opt apparmor=unconfined \ + netdata/netdata +``` + +**Docker Compose**: Copy the following code and paste into a new file called `docker-compose.yml`, then run +`docker-compose up -d` in the same directory as the `docker-compose.yml` file to start the container. + +```yaml +version: '3' +services: + netdata: + image: netdata/netdata + container_name: netdata + hostname: example.com # set to fqdn of host + ports: + - 19999:19999 + restart: unless-stopped + cap_add: + - SYS_PTRACE + security_opt: + - apparmor:unconfined + volumes: + - netdataconfig:/etc/netdata + - netdatalib:/var/lib/netdata + - netdatacache:/var/cache/netdata + - /etc/passwd:/host/etc/passwd:ro + - /etc/group:/host/etc/group:ro + - /proc:/host/proc:ro + - /sys:/host/sys:ro + - /etc/os-release:/host/etc/os-release:ro + +volumes: + netdataconfig: + netdatalib: + netdatacache: +``` + +## Health Checks + +Our Docker image provides integrated support for health checks through the standard Docker interfaces. + +You can control how the health checks run by using the environment variable `NETDATA_HEALTHCHECK_TARGET` as follows: + +- If left unset, the health check will attempt to access the + `/api/v1/info` endpoint of the agent. +- If set to the exact value 'cli', the health check + script will use `netdatacli ping` to determine if the agent is running + correctly or not. This is sufficient to ensure that Netdata did not + hang during startup, but does not provide a rigorous verification + that the daemon is collecting data or is otherwise usable. +- If set to anything else, the health check will treat the value as a + URL to check for a 200 status code on. In most cases, this should + start with `http://localhost:19999/` to check the agent running in + the container. + +In most cases, the default behavior of checking the `/api/v1/info` +endpoint will be sufficient. If you are using a configuration which +disables the web server or restricts access to certain API's, you will +need to use a non-default configuration for health checks to work. + +## Configure Agent containers + +If you started an Agent container using one of the [recommended methods](#create-a-new-netdata-agent-container) and you +want to edit Netdata's configuration, you must first use `docker exec` to attach to the container. Replace `netdata` +with the name of your container. + +```bash +docker exec -it netdata bash +cd /etc/netdata +./edit-config netdata.conf +``` + +You need to restart the Agent to apply changes. Exit the container if you haven't already, then use the `docker` command +to restart the container: `docker restart netdata`. + +### Host-editable configuration + +If you want to make your container's configuration directory accessible from the host system, you need to use a +[volume](https://docs.docker.com/storage/bind-mounts/) rather than a bind mount. The following commands create a +temporary `netdata_tmp` container, which is used to populate a `netdataconfig` directory, which is then mounted inside +the container at `/etc/netdata`. + +```bash +mkdir netdataconfig +docker run -d --name netdata_tmp netdata/netdata +docker cp netdata_tmp:/etc/netdata netdataconfig/ +docker rm -f netdata_tmp +``` + +**`docker run`**: Use the `docker run` command, along with the following options, to start a new container. Note the +changed `-v $(pwd)/netdataconfig/netdata:/etc/netdata:ro \` line from the recommended example above. + +```bash +docker run -d --name=netdata \ + -p 19999:19999 \ + -v $(pwd)/netdataconfig/netdata:/etc/netdata:ro \ + -v netdatalib:/var/lib/netdata \ + -v netdatacache:/var/cache/netdata \ + -v /etc/passwd:/host/etc/passwd:ro \ + -v /etc/group:/host/etc/group:ro \ + -v /proc:/host/proc:ro \ + -v /sys:/host/sys:ro \ + -v /etc/os-release:/host/etc/os-release:ro \ + --restart unless-stopped \ + --cap-add SYS_PTRACE \ + --security-opt apparmor=unconfined \ + netdata/netdata +``` + +**Docker Compose**: Copy the following code and paste into a new file called `docker-compose.yml`, then run +`docker-compose up -d` in the same directory as the `docker-compose.yml` file to start the container. Note the changed +`./netdataconfig/netdata:/etc/netdata:ro` line from the recommended example above. + +```yaml +version: '3' +services: + netdata: + image: netdata/netdata + container_name: netdata + hostname: example.com # set to fqdn of host + ports: + - 19999:19999 + restart: unless-stopped + cap_add: + - SYS_PTRACE + security_opt: + - apparmor:unconfined + volumes: + - ./netdataconfig/netdata:/etc/netdata:ro + - netdatalib:/var/lib/netdata + - netdatacache:/var/cache/netdata + - /etc/passwd:/host/etc/passwd:ro + - /etc/group:/host/etc/group:ro + - /proc:/host/proc:ro + - /sys:/host/sys:ro + - /etc/os-release:/host/etc/os-release:ro + +volumes: + netdatalib: + netdatacache: +``` + +### Change the default hostname + +You can change the hostname of a Docker container, and thus the name that appears in the local dashboard and in Netdata +Cloud, when creating a new container. If you want to change the hostname of a Netdata container _after_ you started it, +you can safely stop and remove it. You configuration and metrics data reside in persistent volumes and are reattached to +the recreated container. + +If you use `docker-run`, use the `--hostname` option with `docker run`. + +```bash +docker run -d --name=netdata \ + --hostname=my_docker_netdata +``` + +If you use `docker-compose`, add a `hostname:` key/value pair into your `docker-compose.yml` file, then create the +container again using `docker-compose up -d`. + +```yaml +version: '3' +services: + netdata: + image: netdata/netdata + container_name: netdata + hostname: my_docker_compose_netdata + ... +``` + +If you don't want to destroy and recreate your container, you can edit the Agent's `netdata.conf` file directly. See the +above section on [configuring Agent containers](#configure-agent-containers) to find the appropriate method based on +how you created the container. + +### Add or remove other volumes + +Some of the volumes are optional depending on how you use Netdata: + +- If you don't want to use the apps.plugin functionality, you can remove the mounts of `/etc/passwd` and `/etc/group` + (they are used to get proper user and group names for the monitored host) to get slightly better security. +- Most modern linux distros supply `/etc/os-release` although some older distros only supply `/etc/lsb-release`. If + this is the case you can change the line above that mounts the file inside the container to + `-v /etc/lsb-release:/host/etc/lsb-release:ro`. +- If your host is virtualized then Netdata cannot detect it from inside the container and will output the wrong + metadata (e.g. on `/api/v1/info` queries). You can fix this by setting a variable that overrides the detection + using, e.g. `--env VIRTUALIZATION=$(systemd-detect-virt -v)`. If you are using a `docker-compose.yml` then add: + +```yaml + environment: + - VIRTUALIZATION=${VIRTUALIZATION} +``` + +This allows the information to be passed into `docker-compose` using: + +```bash +VIRTUALIZATION=$(systemd-detect-virt -v) docker-compose up +``` + +#### Files inside systemd volumes + +If a volume is used by systemd service, some files can be removed during +[reinitialization](https://github.com/netdata/netdata/issues/9916). To avoid this, you need to add +`RuntimeDirectoryPreserve=yes` to the service file. + +### Docker container names resolution + +There are a few options for resolving container names within Netdata. Some methods of doing so will allow root access to +your machine from within the container. Please read the following carefully. + +#### Docker socket proxy (safest option) + +Deploy a Docker socket proxy that accepts and filters out requests using something like +[HAProxy](/docs/Running-behind-haproxy.md) so that it restricts connections to read-only access to the CONTAINERS +endpoint. + +The reason it's safer to expose the socket to the proxy is because Netdata has a TCP port exposed outside the Docker +network. Access to the proxy container is limited to only within the network. + +Below is [an example repository (and image)](https://github.com/Tecnativa/docker-socket-proxy) that provides a proxy to +the socket. + +You run the Docker Socket Proxy in its own Docker Compose file and leave it on a private network that you can add to +other services that require access. + +```yaml +version: '3' +services: + netdata: + image: netdata/netdata + # ... rest of your config ... + ports: + - 19999:19999 + environment: + - DOCKER_HOST=proxy:2375 + proxy: + image: tecnativa/docker-socket-proxy + volumes: + - /var/run/docker.sock:/var/run/docker.sock:ro + environment: + - CONTAINERS=1 + +``` +**Note:** Replace `2375` with the port of your proxy. + +#### Giving group access to the Docker socket (less safe) + +**Important Note**: You should seriously consider the necessity of activating this option, as it grants to the `netdata` +user access to the privileged socket connection of docker service and therefore your whole machine. + +If you want to have your container names resolved by Netdata, make the `netdata` user be part of the group that owns the +socket. + +To achieve that just add environment variable `PGID=[GROUP NUMBER]` to the Netdata container, where `[GROUP NUMBER]` is +practically the group id of the group assigned to the docker socket, on your host. + +This group number can be found by running the following (if socket group ownership is docker): + +```bash +grep docker /etc/group | cut -d ':' -f 3 +``` + +#### Running as root (unsafe) + +> You should seriously consider the necessity of activating this option, as it grants to the `netdata` user access to +> the privileged socket connection of docker service, and therefore your whole machine. + +```yaml +version: '3' +services: + netdata: + image: netdata/netdata + # ... rest of your config ... + volumes: + # ... other volumes ... + - /var/run/docker.sock:/var/run/docker.sock:ro + environment: + - DOCKER_USR=root +``` + +### Pass command line options to Netdata + +Since we use an [ENTRYPOINT](https://docs.docker.com/engine/reference/builder/#entrypoint) directive, you can provide +[Netdata daemon command line options](https://learn.netdata.cloud/docs/agent/daemon/#command-line-options) such as the +IP address Netdata will be running on, using the [command +instruction](https://docs.docker.com/engine/reference/builder/#cmd). + +## Install the Agent using Docker Compose with SSL/TLS enabled HTTP Proxy + +For a permanent installation on a public server, you should [secure the Netdata +instance](/docs/netdata-security.md). This section contains an example of how to install Netdata with an SSL +reverse proxy and basic authentication. + +You can use the following `docker-compose.yml` and Caddyfile files to run Netdata with Docker. Replace the domains and +email address for [Let's Encrypt](https://letsencrypt.org/) before starting. + +### Caddyfile + +This file needs to be placed in `/opt` with name `Caddyfile`. Here you customize your domain and you need to provide +your email address to obtain a Let's Encrypt certificate. Certificate renewal will happen automatically and will be +executed internally by the caddy server. + +```caddyfile +netdata.example.org { + proxy / netdata:19999 + tls admin@example.org +} +``` + +### docker-compose.yml + +After setting Caddyfile run this with `docker-compose up -d` to have fully functioning Netdata setup behind HTTP reverse +proxy. + +```yaml +version: '3' +volumes: + caddy: + +services: + caddy: + image: abiosoft/caddy + ports: + - 80:80 + - 443:443 + volumes: + - /opt/Caddyfile:/etc/Caddyfile + - $HOME/.caddy:/root/.caddy + environment: + ACME_AGREE: 'true' + netdata: + restart: always + hostname: netdata.example.org + image: netdata/netdata + cap_add: + - SYS_PTRACE + security_opt: + - apparmor:unconfined + volumes: + - netdatalib:/var/lib/netdata + - netdatacache:/var/cache/netdata + - /etc/passwd:/host/etc/passwd:ro + - /etc/group:/host/etc/group:ro + - /proc:/host/proc:ro + - /sys:/host/sys:ro + - /var/run/docker.sock:/var/run/docker.sock:ro + +volumes: + netdatalib: + netdatacache: +``` + +### Restrict access with basic auth + +You can restrict access by following [official caddy guide](https://caddyserver.com/docs/caddyfile/directives/basicauth#basicauth) and adding lines to +Caddyfile. + +## Publish a test image to your own repository + +At Netdata, we provide multiple ways of testing your Docker images using your own repositories. +You may either use the command line tools available or take advantage of our Travis CI infrastructure. + +### Inside Netdata organization, using Travis CI + +To enable Travis CI integration on your own repositories (Docker and Github), you need to be part of the Netdata +organization. + +Once you have contacted the Netdata owners to setup you up on Github and Travis, execute the following steps + +- Preparation + - Have Netdata forked on your personal GitHub account + - Get a GitHub token: Go to **GitHub settings** -> **Developer Settings** -> **Personal access tokens**, and + generate a new token with full access to `repo_hook`, read-only access to `admin:org`, `public_repo`, + `repo_deployment`, `repo:status`, and `user:email` settings enabled. This will be your `GITHUB_TOKEN` that is + described later in the instructions, so keep it somewhere safe. + - Contact the Netdata team and seek for permissions on `https://scan.coverity.com` should you require Travis to be + able to push your forked code to coverity for analysis and report. Once you are setup, you should have your + email you used in coverity and a token from them.
