+# Install netdata with Docker
+
+> :warning: As of Sep 9th, 2018 we ship [new docker builds](https://github.com/netdata/netdata/pull/3995), running netdata in docker with 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 is presented by goinbigdata [here](http://goinbigdata.com/docker-run-vs-cmd-vs-entrypoint/) and by docker docs [here](https://docs.docker.com/engine/reference/builder/#understand-how-cmd-and-entrypoint-interact).
+>
+> Also, the `latest` is now based on alpine, so **`alpine` is not updated any more** and `armv7hf` is now replaced with `armhf` (to comply with https://github.com/multiarch naming), so **`armv7hf` is not updated** either.
+
+## Limitations
+
+Running netdata in a container for monitoring the whole host, can limit its capabilities. Some data is not accessible or not as detailed as when running netdata on the host.
+
+## Package scrambling in runtime (x86_64 only)
+
+By default on x86_64 architecture our docker images use Polymorphic Polyverse Linux package scrambling. For increased security you can enable rescrambling of packages during runtime. To do this set environment variable `RESCRAMBLE=true` while starting netdata docker container.
+
+For more information go to [Polyverse site](https://polyverse.io/how-it-works/)
+
+## Run netdata with docker command
+
+Quickly start netdata with the docker command line.
+Netdata is then available at http://host:19999
+
+This is good for an internal network or to quickly analyse a host.
+
+```bash
+docker run -d --name=netdata \
+  -p 19999:19999 \
+  -v /proc:/host/proc:ro \
+  -v /sys:/host/sys:ro \
+  -v /var/run/docker.sock:/var/run/docker.sock:ro \
+  --cap-add SYS_PTRACE \
+  --security-opt apparmor=unconfined \
+  netdata/netdata
+```
+
+The above can be converted to docker-compose file for ease of management:
+
+```yaml
+version: '3'
+services:
+  netdata:
+    image: netdata/netdata
+    hostname: example.com # set to fqdn of host
+    ports:
+      - 19999:19999
+    cap_add:
+      - SYS_PTRACE
+    security_opt:
+      - apparmor:unconfined
+    volumes:
+      - /proc:/host/proc:ro
+      - /sys:/host/sys:ro
+      - /var/run/docker.sock:/var/run/docker.sock:ro
+```
+
+### Docker container names resolution
+
+If you want to have your container names resolved by netdata it needs to have access to docker group. To achive that just add environment variable `PGID=999` to netdata container, where `999` is a docker group id from your host. This number can be found by running:
+```bash
+grep docker /etc/group | cut -d ':' -f 3
+```
+
+### 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://docs.netdata.cloud/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 Netdata 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 use the following docker-compose.yml and Caddyfile files to run netdata with docker. Replace the Domains and email address for [Letsencrypt](https://letsencrypt.org/) before starting.
+
+### Prerequisites
+* [Docker](https://docs.docker.com/install/#server)
+* [Docker Compose](https://docs.docker.com/compose/install/)
+* Domain configured in DNS pointing to host.
+
+### 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 Letsencrypt certificate. Certificate renewal will happen automatically and will be executed internally by the caddy server.
+
+```
+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
+      - 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:
+      - /proc:/host/proc:ro
+      - /sys:/host/sys:ro
+      - /var/run/docker.sock:/var/run/docker.sock:ro
+```
+
+### Restrict access with basic auth
+
+You can restrict access by following [official caddy guide](https://caddyserver.com/docs/basicauth) and adding lines to Caddyfile.
