Preparation

Axiomatics Services Manager is downloaded via AWS CLI. If you have not already done so, install AWS CLI following the instructions in AWS documentationOpens in a new tab.

1. Configure the Axiomatics AWS CLI account using the aws configure command, as explained in the AWS documentationOpens in a new tab. This procedure requires an Access key ID and a Secret access key, which will have been provided to you by Axiomatics.

   tip

   Optionally, you can create and use profiles to store these settings, as described in this AWS help pageOpens in a new tab. This could come in handy in deployments using a remote registry which requires an additional AWS CLI account from your side.

2. The ASM distribution is downloaded as a ZIP file, containing a pre-configured Docker-based installation. Run the following command in the terminal to download ASM:

   aws s3api get-object --bucket axiomatics-customer-artifacts --key releases/com/axiomatics/axiomatics-services-manager/axiomatics-services-manager/7.4.1-0/axiomatics-services-manager-7.4.1-0.zip axiomatics-services-manager-7.4.1-0.zip

Docker registry

The Docker registry is a server side application that stores and lets you distribute Docker images. It is recommended to work with the remote registry provided by Axiomatics, or optionally your own remote registry. However, for local installations only, if a remote registry cannot be supported by your specific setup, then you can deploy a local registry server.

Follow the steps below according to your specific setup:

Axiomatics registry

Log in to the Amazon ECR registry provided by Axiomatics.

aws ecr get-login-password --region eu-central-1 | docker login --username AWS --password-stdin 748131003707.dkr.ecr.eu-central-1.amazonaws.com

Remote registry

Important

In the snippet below replace

• <region_code> with the AWS Region that you want to create your cluster in
• <aws_account_id> with your AWS account ID

1. Configure your AWS CLI account using the aws configure command, as explained in the AWS documentationOpens in a new tab.

2. Log in to your Amazon ECR registry.

   aws ecr get-login-password --region <region_code> | docker login --username AWS --password-stdin <aws_account_id>.dkr.ecr.<region_code>.amazonaws.com

3. Create the following repositories in your ECR registry, as described in the AWS documentationOpens in a new tab:

   axiomatics/adm
   axiomatics/api-gateway
   axiomatics/asm-core
   axiomatics/postgres
   axiomatics/influxdb
   axiomatics/pd-api
   axiomatics/pd-ui
   axiomatics/keycloak-mappers
   axiomatics/service-aggregator

Local registry

Important

In the snippets below replace <hostname> with your own hostname. In case you do not have a hostname and you are working with localhost, add the special domain host.docker.internal.

1. Create a directory.

   mkdir certs

2. Create a self-signed certificate.

   openssl req -x509 -newkey rsa:4096 -sha256 -days 3650 -nodes -keyout certs/registry.key -out certs/registry.crt -subj "/CN=<hostname>" -addext "subjectAltName=DNS:<hostname>"

3. Add the certificate to Docker trusted certificates. Based on your OS:

   • Windows:

     Install the registry.crt certificate on your Local machine in the Trusted Root Certification Authorities.

   • macOS and Linux:

     1. Create the certificates directory, if it doesn't exist already.

        sudo mkdir -p /etc/docker/certs.d/<hostname>:5000

     2. Copy the generated certificate to the Docker certificates directory.

        sudo cp certs/registry.crt /etc/docker/certs.d/<hostname>:5000/ca.crt

4. Restart Docker.

5. Start the local registry from the parent directory of the certs folder.

   docker run -d -p 5000:5000 --restart=always --name registry -v "$(pwd)"/certs:/certs -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/registry.crt -e REGISTRY_HTTP_TLS_KEY=/certs/registry.key registry:2 

6. Create a PEM file and copy it to the Minikube configurations directory.

   openssl x509 -in certs/registry.crt -out certs/registry.pem -outform PEM 

   cp certs/registry.pem ~/.minikube/certs

Docker image

Important

If you are using the Axiomatics registry you should skip this section. However, if you are using your own remote or local registry, the steps below are required.

Build and push the Docker image

1. Extract the ASM distribution ZIP file to the folder from where you want to run ASM.

2. Navigate to the docker folder of the extracted distribution.

   1. Open the credentials.txt file and update the placeholder values for Access key ID and Secret access key with the values provided by Axiomatics.

      note

      These are the same values that were used in setting up AWS CLI.

   2. Open the .env file and add your registry.

      Remote registry

      REGISTRY=<aws_account_id>.dkr.ecr.<region_code>.amazonaws.com/axiomatics/

      Local registry

      REGISTRY=localhost:5000/

   3. Optionally, for deployments that include Access Decision Service (ADS):

      Add your hostname

      Open the .env file and update the values of HOST and CERTIFICATE_CN with your own hostname.

      note

      In case you are working with localhost, use the special domain host.docker.internal.

3. Enable the BuildKit feature of Docker:

   Windows

   $Env:DOCKER_BUILDKIT=1

   Linux/macOS

   export DOCKER_BUILDKIT=1

4. Run the following command to build ASM.

   docker-compose -f docker-compose.yml -f docker-compose.dashboard.yml build 

5. Run the following command to push the image to your registry.

   docker-compose -f docker-compose.yml -f docker-compose.dashboard.yml push

SSL Certificate

In production environments, you should import trusted certificates only, while in dev and test environments you have the ability to create a self-signed certificate.

Import

ASM requires a PKCS#12 (Public Key Cryptography Standard #12) certificate. In case you already have a certificate with different format such as .pem, you should convert it to PKCS#12. The certificate file must be named cert.keystore.p12. During the creation of the certificate, the name (or alias) must be set to server.

1. Navigate to the docker/api.gateway/certs/ folder of the extracted distribution.
2. Copy your certificate to this folder.

Create

Generate a self-signed certificate as follows:

1. Navigate to the docker folder of the extracted distribution.

2. Open the .env file and update the following entries:

   • CERTIFICATE_CN with your common name
   • CERTIFICATE_KEY_STORE_PASSWORD with your password

3. Generate the certificate:

Linux/macOS

1. From the docker/api.gateway/certs/ folder, run the following command.

sh generate_self_signed_certificate.sh

2. Make sure that the following files were created:

• cert.keystore.p12
• server.crt

Windows

1. From the docker\api.gateway\certs folder, run the following commands using PowerShell.

Important

In the first command, replace <your_cert_key_store_pw> and <your_cert_cn> with the same values that were previously used in the .env file.

docker build -t certificate -f ./Dockerfile.cert . --build-arg CERTIFICATE_KEY_STORE_PASSWORD=<your_cert_key_store_pw> --build-arg CERTIFICATE_CN=<your_cert_cn>

docker create --name cert certificate; docker cp cert:/cert.keystore.p12 ./cert.keystore.p12; docker cp cert:/server.crt ./server.crt; docker rm -f cert; docker image rm certificate

2. Make sure that the following files were created:
   • cert.keystore.p12
   • server.crt

ASM K8s installation

Local installation

1. Navigate to the kubernetes directory.

   Add the axiomatics_ASM.license license file and launch a terminal window in this directory.

2. Run the following command to start minikube.

   minikube start
   #In case the system is slow, use the following command instead:
   minikube start --memory 4096

3. After minikube has started, launch a new terminal window and create a tunnel.

   minikube tunnel
   Important

   This terminal window should remain open during the K8s installation.

4. On the initial terminal window, create the ASM namespace.

   kubectl create namespace axiomatics-asm

   kubectl get all -n axiomatics-asm

Troubleshooting

Extra commands that could assist your troubleshooting effort.

Important

In the snippets below replace

• <region_code> with your cluster's AWS Region
• <aws_account_id> with your AWS account ID

Kubernetes statuses

ErrImagePull

If the pod status is ErrImagePull because of an expired registry credentials secret:

1. Delete secret.

   kubectl delete secret regcred -n axiomatics-asm
2. Recreate it.

   kubectl create secret docker-registry regcred --docker-server=<aws_account_id>.dkr.ecr.<region_code>.amazonaws.com --docker-username=AWS --docker-password=$(aws ecr get-login-password) --namespace=axiomatics-asm 

ImagePullBackOff

The status ImagePullBackOff means that the ECR Docker image is too large and cannot be downloaded. To resolve this issue, use the following commands to download the required image within minikube.

Important

Replace the placeholders with the appropriate values before running the commands.

minikube ssh
su - root # Default password is 'root'
apt-get update
apt-get install unzip  
curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
unzip awscliv2.zip
sudo ./aws/install 
aws configure # Provide AWS Access Key ID and AWS Secret Access Key
aws ecr get-login-password --region <region_code> | docker login --username AWS --password-stdin <aws_account_id>.dkr.ecr.<region_code>.amazonaws.com
docker pull <aws_account_id>.dkr.ecr.<region_code>.amazonaws.com/axiomatics/asm-core:<version> 

What's next?

Add users

During the deployment, a Keycloak service was also installed, to serve as an authentication module for the users of ASM. Only a default administrative user is created automatically at this time. All other users must be created and assigned a role in Keycloak, before they can log in to ASM.

To add more users and map them to roles you must use Keycloak as described in Manage users in Keycloak. Then, you can assign them to projects following the instructions in the Users and projects topic.

Important

For deployments with Policy Designer, you should also configure Keycloak accordingly.

Additional configuration

Once the installation of ASM has been verified as successful, there are additional configurations you may want to consider.
