# Bitnami package for ASP.NET Core ## What is ASP.NET Core? > ASP.NET Core is an open-source framework for web application development created by Microsoft. It runs on both the full .NET Framework, on Windows, and the cross-platform .NET Core. [Overview of ASP.NET Core](https://github.com/dotnet/aspnetcore) Trademarks: This software listing is packaged by Bitnami. The respective trademarks mentioned in the offering are owned by the respective companies, and use of them does not imply any affiliation or endorsement. ## TL;DR ```console docker run --name aspnet-core bitnami/aspnet-core:latest ``` ## Why use Bitnami Images? * Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems. * With Bitnami images the latest bug fixes and features are available as soon as possible. * Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs. * All our images are based on [**minideb**](https://github.com/bitnami/minideb) -a minimalist Debian based container image that gives you a small base container image and the familiarity of a leading Linux distribution- or **scratch** -an explicitly empty image-. * All Bitnami images available in Docker Hub are signed with [Notation](https://notaryproject.dev/). [Check this post](https://blog.bitnami.com/2024/03/bitnami-packaged-containers-and-helm.html) to know how to verify the integrity of the images. * Bitnami container images are released on a regular basis with the latest distribution packages available. Looking to use ASP.NET Core in production? Try [VMware Tanzu Application Catalog](https://bitnami.com/enterprise), the commercial edition of the Bitnami catalog. ## Only the latest stable branch maintained in the free Bitnami catalog Starting December 10th, 2024, only the latest stable branch of each container image will receive updates in the free Bitnami catalog. To access up-to-date releases for all upstream-supported branches (e.g., LTS), consider upgrading to Bitnami Premium. Previously released versions will not be deleted and will remain available for pulling from DockerHub. Please check the Bitnami Premium page in our partner [Arrow Electronics](https://www.arrow.com/globalecs/na/vendors/bitnami?utm_source=GitHub&utm_medium=containers) for more information. ## Supported tags and respective `Dockerfile` links Learn more about the Bitnami tagging policy and the difference between rolling tags and immutable tags [in our documentation page](https://techdocs.broadcom.com/us/en/vmware-tanzu/application-catalog/tanzu-application-catalog/services/tac-doc/apps-tutorials-understand-rolling-tags-containers-index.html). You can see the equivalence between the different tags by taking a look at the `tags-info.yaml` file present in the branch folder, i.e `bitnami/ASSET/BRANCH/DISTRO/tags-info.yaml`. Subscribe to project updates by watching the [bitnami/containers GitHub repo](https://github.com/bitnami/containers). ## Get this image The recommended way to get the Bitnami aspnet-core Docker Image is to pull the prebuilt image from the [Docker Hub Registry](https://hub.docker.com/r/bitnami/aspnet-core). ```console docker pull bitnami/aspnet-core:latest ``` To use a specific version, you can pull a versioned tag. You can view the [list of available versions](https://hub.docker.com/r/bitnami/aspnet-core/tags/) in the Docker Hub Registry. ```console docker pull bitnami/aspnet-core:[TAG] ``` If you wish, you can also build the image yourself by cloning the repository, changing to the directory containing the Dockerfile and executing the `docker build` command. Remember to replace the `APP`, `VERSION` and `OPERATING-SYSTEM` path placeholders in the example command below with the correct values. ```console git clone https://github.com/bitnami/containers.git cd bitnami/APP/VERSION/OPERATING-SYSTEM docker build -t bitnami/APP:latest . ``` ## Persisting your application If you remove the container all your data will be lost, and the next time you run the image the database will be reinitialized. To avoid this loss of data, you should mount a volume that will persist even after the container is removed. For persistence you should mount a directory at the `/app` path. If the mounted directory is empty, it will be initialized on the first run. ```console docker run \ -v /path/to/aspnet-core-persistence:/app \ bitnami/aspnet-core:latest ``` You can also do this with a minor change to the [`docker-compose.yml`](https://github.com/bitnami/containers/blob/main/bitnami/aspnet-core/docker-compose.yml) file present in this repository: ```yaml aspnet-core: ... volumes: - /path/to/aspnet-core-persistence:/app ... ``` ## Connecting to other containers Using [Docker container networking](https://docs.docker.com/engine/userguide/networking/), a different server running inside a container can easily be accessed by your application containers and vice-versa. Containers attached to the same network can communicate with each other using the container name as the hostname. ### Using the Command Line #### Step 1: Create a network ```console docker network create aspnet-core-network --driver bridge ``` #### Step 2: Launch the aspnet-core container within your network Use the `--network ` argument to the `docker run` command to attach the container to the `aspnet-core-network` network. ```console docker run --name aspnet-core-node1 --network aspnet-core-network bitnami/aspnet-core:latest ``` #### Step 3: Run another containers We can launch another containers using the same flag (`--network NETWORK`) in the `docker run` command. If you also set a name to your container, you will be able to use it as hostname in your network. ## Logging The Bitnami aspnet-core Docker image sends the container logs to `stdout`. To view the logs: ```console docker logs aspnet-core ``` You can configure the containers [logging driver](https://docs.docker.com/engine/admin/logging/overview/) using the `--log-driver` option if you wish to consume the container logs differently. In the default configuration docker uses the `json-file` driver. ## Maintenance ### Upgrade this image Bitnami provides up-to-date versions of aspnet-core, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container. #### Step 1: Get the updated image ```console docker pull bitnami/aspnet-core:latest ``` #### Step 2: Stop the running container Stop the currently running container using the command ```console docker stop aspnet-core ``` #### Step 3: Remove the currently running container ```console docker rm -v aspnet-core ``` #### Step 4: Run the new image Re-create your container from the new image. ```console docker run --name aspnet-core bitnami/aspnet-core:latest ``` ## Using `docker-compose.yaml` Please be aware this file has not undergone internal testing. Consequently, we advise its use exclusively for development or testing purposes. For production-ready deployments, we highly recommend utilizing its associated [Bitnami Helm chart](https://github.com/bitnami/charts/tree/main/bitnami/aspnet-core). If you detect any issue in the `docker-compose.yaml` file, feel free to report it or contribute with a fix by following our [Contributing Guidelines](https://github.com/bitnami/containers/blob/main/CONTRIBUTING.md). ## Contributing We'd love for you to contribute to this container.
