Why use Bitnami Secure Images?

Those are hardened, minimal CVE images built and maintained by Bitnami. Bitnami Secure Images are based on the cloud-optimized, security-hardened enterprise https://vmware.github.io/photon/. Why choose BSI images?

• Hardened secure images of popular open source software with Near-Zero Vulnerabilities
• Vulnerability Triage & Prioritization with VEX Statements, KEV and EPSS Scores
• Compliance focus with FIPS, STIG, and air-gap options, including secure bill of materials (SBOM)
• Software supply chain provenance attestation through in-toto
• First class support for the internet’s favorite Helm charts

Each image comes with valuable security metadata. You can view the metadata in our public catalog here. Note: Some data is only available with commercial subscriptions to BSI.

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.

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.

Get this image

The recommended way to get the Bitnami Dotnet Docker Image is to pull the prebuilt image from the https://hub.docker.com/r/bitnami/dotnet.

console
docker pull bitnami/dotnet:latest

To use a specific version, you can pull a versioned tag. You can view the https://hub.docker.com/r/bitnami/dotnet/tags/ in the Docker Hub Registry.

console
docker pull bitnami/dotnet:[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 /bitnami path. If the mounted directory is empty, it will be initialized on the first run.

console
docker run \
    -v /path/to/dotnet-persistence:/bitnami \
    bitnami/dotnet:latest

You can also do this with a minor change to the https://github.com/bitnami/containers/blob/main/bitnami/dotnet/docker-compose.yml file present in this repository:

yaml
dotnet:
  ...
  volumes:
    - /path/to/dotnet-persistence:/bitnami
  ...

Connecting to other containers

Using Docker container 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 dotnet-network --driver bridge

Step 2: Launch the Dotnet container within your network

Use the --network .NETWORK> argument to the docker run command to attach the container to the dotnet-network network.

console
docker run --name dotnet-node1 --network dotnet-network bitnami/dotnet: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.

Configuration

FIPS configuration in Bitnami Secure Images

The Bitnami .NET Docker image from the Bitnami Secure Images catalog includes extra features and settings to configure the container with FIPS capabilities. You can configure the next environment variables:

• OPENSSL_FIPS: whether OpenSSL runs in FIPS mode or not. yes (default), no.

Logging

The Bitnami Dotnet Docker image sends the container logs to stdout. To view the logs:

console
docker logs dotnet

You can configure the containers logging driver 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 Dotnet, 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/dotnet:latest

Step 2: Stop the running container

Stop the currently running container using the command

console
docker stop dotnet

Step 3: Remove the currently running container

console
docker rm -v dotnet

Step 4: Run the new image

Re-create your container from the new image.

console
docker run --name dotnet bitnami/dotnet:latest
