# Update the Netdata Agent By default, the Netdata Agent automatically updates with the latest nightly version. If you opted out of automatic updates, you need to update your Netdata Agent to the latest nightly or stable version. > 💡 Looking to reinstall the Netdata Agent to enable a feature, update an Agent that cannot update automatically, or > troubleshoot an error during the installation process? See our [reinstallation doc](/packaging/installer/REINSTALL.md) > for reinstallation steps. Before you update the Netdata Agent, check to see if your Netdata Agent is already up-to-date by clicking on the update icon in the local Agent dashboard's top navigation. This modal informs you whether your Agent needs an update or not. ![Opening the Agent's Update modal](https://user-images.githubusercontent.com/1153921/99738428-add06780-2a87-11eb-8268-0e17b689eb3f.gif) ## Determine which installation method you used If you are not sure where your Netdata config directory is, see the [configuration doc](/docs/configure/nodes.md). In most installations, this is `/etc/netdata`. Use `cd` to navigate to the Netdata config directory, then use `ls -a` to look for a file called `.install-type`. - If the `.install-type` file doex not exist, look for a file in the same directory called `.environment`. - If the `.environment` file does not exist, you probably installed Netdata using your system package manager and should update it the same way you would run updates on the system itself. - If the `.environment` file does exist, then our [regular update method](#updates-for-most-systems) should work correctly. - If the `.install-type` file does exist, check it’s contents with `cat .install-type`. - If the `INSTALL_TYPE` key has a value of `custom`, you probably installed Netdata using your system package manager and should update it the same way you would run updates on the system itself. - If the `INSTALL_TYPE` key has a value of `oci`, the install is from a Docker image. - Otherwise, the install should work with our [regular update method](#updates-for-most-systems). Next, use the appropriate method to update the Netdata Agent: - [Updates for most systems](#updates-for-most-systems) - [Docker](#docker) - [macOS](#macos) - [Manual installation from Git](#manual-installation-from-git) ## Updates for most systems In most cases, you can update netdata using our one-line installation script. This script will automatically run the update script that was installed as part of the initial install (even if you disabled automatic updates) and preserve the existing install options you specified. If you installed Netdata using an installation prefix, you will need to add an `--install` option specifying that prefix to this command to make sure it finds Netdata. ```bash wget -O /tmp/netdata-kickstart.sh https://my-netdata.io/kickstart.sh && sh /tmp/netdata-kickstart.sh ``` > ❗ If the above command fails, you can [reinstall > Netdata](/packaging/installer/REINSTALL.md#one-line-installer-script-kickstartsh) to get the latest version. This also > preserves your [configuration](/docs/configure/nodes.md) in `netdata.conf` or other files. ## Docker Docker-based installations do not update automatically. To update an Netdata Agent running in a Docker container, you must pull the [latest image from Docker Hub](https://hub.docker.com/r/netdata/netdata), stop and remove the container, and re-create it using the latest image. First, pull the latest version of the image. ```bash docker pull netdata/netdata:latest ``` Next, to stop and remove any containers using the `netdata/netdata` image. Replace `netdata` if you changed it from the default. ```bash docker stop netdata docker rm netdata ``` You can now re-create your Netdata container using the `docker` command or a `docker-compose.yml` file. See our [Docker installation instructions](/packaging/docker/README.md#create-a-new-netdata-agent-container) for details. ## macOS If you installed Netdata on your macOS system using Homebrew, you can explicitly request an update: ```bash brew upgrade netdata ``` Homebrew downloads the latest Netdata via the [formulae](https://github.com/Homebrew/homebrew-core/blob/master/Formula/netdata.rb), ensures all dependencies are met, and updates Netdata via reinstallation. ## Manual installation from Git If you installed [Netdata manually from Git](/packaging/installer/methods/manual.md), you can run that installer again to update your agent. First, run our automatic requirements installer, which works on many Linux distributions, to ensure your system has the dependencies necessary for new features. ```bash bash <(curl -sSL https://raw.githubusercontent.com/netdata/netdata/master/packaging/installer/install-required-packages.sh) ``` Navigate to the directory where you first cloned the Netdata repository, pull the latest source code, and run `netdata-install.sh` again. This process compiles Netdata with the latest source code and updates it via reinstallation. ```bash cd /path/to/netdata/git git pull origin master sudo ./netdata-installer.sh ``` > ⚠️ If you installed Netdata with any optional parameters, such as `--no-updates` to disable automatic updates, and > want to retain those settings, you need to set them again during this process.
