Troubleshoot Docker installation issues

This section describes some of the most common issues found during the Akamas installation.

Issues when installing Docker

Centos 7 and RHEL 7

Notice: this distro features a known issue since Docker default execution group is named dockerroot instead of docker . To make docker work edit (or create) /etc/docker/daemon.json to include the following fragment:

{
  "group": "dockerroot"
}

After editing or creating the file, please restart Docker and then check the group permission of the Docker socket (/var/run/docker.sock), which should show dockerroot as a group:

srw-rw----. 1 root dockerroot 0 Jul  4 09:57 /var/run/docker.sock

Then, add the newly created akamas user to the dockerroot group so that it can run docker containers:

sudo usermod -aG dockerroot <user_name>

and check the akamas user has been correctly added to dockerroot group by running:

lid -g dockerroot

Issues when running AWS CLI

In case of issues in logging in through AWS CLI, when executing the following command:

aws ecr get-login-password --region us-east-2

Please check that:

  • Environment variables AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_DEFAULT_REGION are correctly set

  • AWS CLI version is 2.0+

We recommend using the official AWS CLI installation guide for a smoother experience.

Issue when starting Akamas services

Akamas failed to start some services

Please notice that the very first time Akamas is started, up to 30 minutes might be required to initialize the environment.

In case the issue persists you can run the following command to identify which service is not able to start up correctly

akamas status -d

License service unable to access docker socket

In some systems, the Docker socket, usually located in /var/run/docker.sock can not be accessed within a container. This causes Akamas to signal this behavior by reporting the Access Denied error in the license service logs.

To overcome this limitation edit the docker-compose.yaml file adding the line privileged: true to the following services:

  • License

  • Optimizer

  • Telemetry

  • Airflow

The following is a sample configuration where this change is applied to the license service:

license:
  image: 485790562880.dkr.ecr.us-east-2.amazonaws.com/akamas/license_service:2.3.0
  container_name: license
  privileged: true

Finally, you can issue the following command to apply these changes

docker-compose up -d

Missing Akamas Customer variable

When installing Akamas it’s mandatory to export the AKAMAS_CUSTOMER variable as illustrated in the installation guide. This variable must match the one provided by Akamas representatives when issuing a license. If the variable is not properly exported license installation will fail with an error message indicating that the name of the customer installation does not match the one provided in the license.

You can easily inspect which value of this variable has been used when starting Akamas by running the following command on the Akamas server:

docker inspect license | grep AKAMAS_CUSTOMER

If you find out that the value is not the one you expect you can change it by running the following command on the Akamas server:

AKAMAS_CUSTOMER=<your-new-value> docker-compose up -d license

Once Akamas is up and running you can re-install your license.

For any other issues please contact Akamas Customer Support Services.
