Deploying the Access#

This section describes how to install and use Docker Compose to deploy the Service.

Docker and Docker Compose are not included in the Service distribution package.

Docker allows you to create a container that already has the required Service, the software environment for it and the minimum set of necessary tools. Docker Compose is used to automatically deploy containers.

Docker and Docker Compose installation#

Use the official instructions to install Docker Engine and Docker Compose for CentOS. The current installation instructions are presented below.

1․ Install the yum-utils package (which provides the yum-config-manager utility):

sudo yum install -y yum-utils

2․ Set up the stable repository:

sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

3․ Install the latest version of Docker Engine and containerd:

sudo yum install docker-ce docker-ce-cli containerd.io

4․ Check that the installation was done correctly:

docker -v

5․ Download the current stable release of Docker Compose:

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

6․ Apply executable permissions to the binary:

sudo chmod +x /usr/local/bin/docker-compose

7․ Start Docker:

systemctl start docker
systemctl enable docker

8․ Check Docker status:

systemctl status docker

Response must contain Active (running) status.

Preparing and unpacking the distribution#

The distribution package is an archive of the form «vl-access-2-vX.Y.ZZ», where «X.Y.ZZ» is a numerical identifier indicating the version of the product.

A link to download the distribution kit must be requested from a VisionLabs representative.

The archive contains all the components necessary for the installation and operation of the Service.

The archive does not include dependencies that are included in the standard distribution package of the CentOS 7.4 x86_64 repository and can be downloaded from open sources.

The Service is launched from a Docker image.

Follow these steps.

1․ Install the unzip archiver if it is not installed. Version 6.0-21 is specified in the command, errors were noticed in the work of later versions:

yum install unzip-6.0-21.el7

2․ Unpack files:

unzip vl-access-2-vX.Y.ZZ.zip -d vl-access

3․ After unpacking, a directory will appear containing:

  • README_FOR_ENGINEERS.md file with description of quick start;
  • .env configuration file.
  • docker-compose.yml configuration file;
  • CHANGELOG.md changelog;
  • vl_access_2_vX.Y.ZZ.tar.gz image archive

4․ In case of changing the location of the database firmware in docker-compose, run the command to access the PostgreSQL data storage from the container (execute one time for the image):

docker volume create --name=db_data
