-Dozzle is a log viewer for Docker. It's free. It's small. And it's right in your browser. Oh, did I mention it is also real-time?
+Dozzle is a small lightweight application with a web based interface to monitor Docker logs. It doesn’t store any log files. It is for live monitoring of your container logs only.
 
-While dozzle should work for most, it is not meant to be a full logging solution. For enterprise use, I recommend you look at [Loggly](https://www.loggly.com), [Papertrail](https://papertrailapp.com) or [Kibana](https://www.elastic.co/products/kibana).
+![Image](https://github.com/amir20/dozzle/blob/master/.github/demo.gif?raw=true)
 
-But if you don't want to pay for those services, then you are in luck! Dozzle will be able to capture all logs from your containers and send them in real-time to your browser. Installation is also very easy.

+## Features
 
-## Getting dozzle
+- Intelligent fuzzy search for container names 🤖
+- Search logs using regex 🔦
+- Small memory footprint 🏎
+- Split screen for viewing multiple logs
+- Download logs easy
+- Live stats with memory and CPU usage
+- Authentication with username and password 🚨
+
+Dozzle should work for most. It has been tested with hundreds of containers. However, it doesn't support offline searching. Products like [Loggly](https://www.loggly.com), [Papertrail](https://papertrailapp.com) or [Kibana](https://www.elastic.co/products/kibana) are more suited for full search capabilities.
+
+Dozzle doesn't cost any money and aims to focus on real-time debugging.
+
+## Getting Dozzle
 
 Dozzle is a very small Docker container (4 MB compressed). Pull the latest release from the index:
 
     $ docker pull amir20/dozzle:latest
 
-## Using dozzle
+## Using Dozzle
 
-The simplest way to use dozzle is to run the docker container. Also, mount the Docker Unix socket with `-volume` to `/var/run/docker.sock`:
+The simplest way to use dozzle is to run the docker container. Also, mount the Docker Unix socket with `--volume` to `/var/run/docker.sock`:
 
     $ docker run --name dozzle -d --volume=/var/run/docker.sock:/var/run/docker.sock -p 8888:8080 amir20/dozzle:latest
 
-dozzle will be available at [http://localhost:8888/](http://localhost:8888/). You can change `-p 8888:8080` to any port. For example, if you want to view dozzle over port 4040 then you would do `-p 4040:8080`.

+
+    docker service create \
+    --name=dozzle \
+    --publish=8888:8080 \
+    --constraint=node.role==manager \
+    --mount=type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock \

+
+    version: "3"
+    services:
+      dozzle:
+        container_name: dozzle
+        image: amir20/dozzle:latest
+        volumes:
+          - /var/run/docker.sock:/var/run/docker.sock
+        ports:
+          - 9999:8080
 
 #### Security
 
-dozzle doesn't support authentication out of the box. You can control the device dozzle binds to by passing `--addr` parameter. For example,
+You can control the device Dozzle binds to by passing `--addr` parameter. For example,
 
     $ docker run --volume=/var/run/docker.sock:/var/run/docker.sock -p 8888:1224 amir20/dozzle:latest --addr localhost:1224
 
 will bind to `localhost` on port `1224`. You can then use a reverse proxy to control who can see dozzle.
 
+If you wish to restrict the containers shown you can pass the `--filter` parameter. For example,
+
+    $ docker run --volume=/var/run/docker.sock:/var/run/docker.sock -p 8888:1224 amir20/dozzle:latest --filter name=foo
+
+this would then only allow you to view containers with a name starting with "foo". You can use other filters like `status` as well, please check the official docker [command line docs](https://docs.docker.com/engine/reference/commandline/ps/#filtering) for available filters. Multiple `--filter` arguments can be provided.
+
+#### Authentication
+
+Dozzle supports a very simple authentication out of the box with just username and password. You should deploy using SSL to keep the credentials safe. See configuration to use `--username` and `--password`.

+#### Analytics collected
 
-#### Environment variable, DOCKER_API_VERSION
+Dozzle collects anonymous user configurations using Google Analytics. Why? Dozzle is an open source project with no funding. As a result, there is no time to do user studies of Dozzle. Analytics is collected to prioritize features and fixes based on how people use Dozzle. This data is completely public and can be viewed live using [ Data Studio dashboard](https://datastudio.google.com/s/naeIu0MiWsY).
 
-If you see
+If you do not want to be tracked at all, see the `--no-analytics` flag below.
 
-    2018/10/31 08:53:17 Error response from daemon: client version 1.40 is too new. Maximum supported API version is 1.38
+#### Environment variables and configuration
 
-Then you need to modify `DOCKER_API_VERSION` to let dozzle know which version of the API is supported. By default, `DOCKER_API_VERSION=1.38` and you can change it by passing `-e` flag. For example, this would change the `DOCKER_API_VERSION` to `1.20`
+Dozzle follows the [12-factor](https://12factor.net/) model. Configurations can use the CLI flags or environment variables. The table below outlines all supported options and their respective env vars.
 
-    $ docker run --volume=/var/run/docker.sock:/var/run/docker.sock -e DOCKER_API_VERSION=1.20 -p 8888:8080 amir20/dozzle:latest
+| Flag             | Env Variable          | Default |
+| ---------------- | --------------------- | ------- |
+| `--addr`         | `DOZZLE_ADDR`         | `:8080` |
+| `--base`         | `DOZZLE_BASE`         | `/`     |
+| `--level`        | `DOZZLE_LEVEL`        | `info`  |
+| n/a              | `DOCKER_API_VERSION`  | not set |
+| `--tailSize`     | `DOZZLE_TAILSIZE`     | `300`   |
+| `--filter`       | `DOZZLE_FILTER`       | `""`    |
+| `--username`     | `DOZZLE_USERNAME`     | `""`    |
+| `--password`     | `DOZZLE_PASSWORD`     | `""`    |
+| `--key`          | `DOZZLE_KEY`          | `""`    |
+| `--no-analytics` | `DOZZLE_NO_ANALYTICS` | false   |
 
-If you are not sure what to set `DOCKER_API_VERSION` then run `docker version` which will show supported API version.
+Note: When using username and password `DOZZLE_KEY` is required for session management.
+
+## Troubleshooting and FAQs
+
+<details>
+ <summary>I installed Dozzle, but logs are slow or they never load. Help!</summary>
+
+Dozzle uses Server Sent Events (SSE) which connects to a server using a HTTP stream without closing the connection. If any proxy tries to buffer this connection, then Dozzle never receives the data and hangs forever waiting for the reverse proxy to flush the buffer. Since version `1.23.0`, Dozzle sends the `X-Accel-Buffering: no` header which should stop reverse proxies buffering. However, some proxies may ignore this header. In those cases, you need to explicitly disable any buffering.
+
+Below is an example with nginx and using `proxy_pass` to disable buffering.
+
+```
+    server {
+        ...
+
+        location / {
+            proxy_pass                  http://<dozzle.container.ip.address>:8080;
+        }
+
+        location /api {
+            proxy_pass                  http://<dozzle.container.ip.address>:8080;
+
+            proxy_buffering             off;
+            proxy_cache                 off;
+        }
+    }
+
+```
+
+</details>
+
+<details>
+ <summary>What data does Dozzle collect?</summary>
+
+Dozzle does collect some analytics. Analytics is anonymous usage tracking of the features which are used the most. See the section above on how to disable any analytic collection.
+
+In the browser, Dozzle has a [strict](https://github.com/amir20/dozzle/blob/master/web/csp.go#L9) Content Security Policy which only allows the following policies:
+
+- Allow connect to `api.github.com` to fetch most recent version.
+- Only allow `<script>` and `<style>` files from `self`
+
+Dozzle opens all links with `rel="noopener"`.
+
+</details>
+
+<details>
+ <summary>We have tools that uses Dozzle when a new container is created. How can I get a direct link to a container by name?</summary>
+
+Dozzle has a [special route](https://github.com/amir20/dozzle/blob/master/assets/pages/Show.vue) that can be used to search containers by name and then forward to that container. For example, if you have a container with name `"foo.bar"` and id `abc123`, you can send your users to `/show?name=foo.bar` which will be forwarded to `/container/abc123`.
