Upgrading Docker Compose

Upgrade your Docker Compose installation.

Before you begin

HCL™ Accelerate installation properties are stored in the /home/.ucv/settings.json file on the computer where you installed the product. If the user that is upgrading the product is not the user who installed it, ensure that the settings.json file is copied to the upgrading user's /home/.ucv directory before upgrading.

About this task

When you run the installer, it checks for an existing installation. If the installer finds a previous version, it uses installed properties, such as your product access key, and assumes that you are upgrading the product.

Prerequisites

Consult the system requirements and ensure your existing environment that meets HCL™ Accelerate needs. See system requirements.
Consult the upgrade notes for the latest information that must be considered before starting upgrading. For example, MongoDB migration.
MongoDB Download (Applicable for Offline installation only) Before starting the installation, pull the MongoDB images from the MongoDB sources. Complete the following steps to pull the MongoDB images. If you are using the online install, then this step is completely automatically.
1. Run the docker pull mongo:<mongodb_version_number> && docker save -o mongo.tar mongo:<mongodb_version_number> command to pull image for MongoDB.
  Note: For more information about compatible versions of MongoDB, see system requirements page.
2. Copy the mongo.tar to offline installation system and run the docker load -i mongo.tar command to load the docker images.

Upgrade

The upgrade instructions describe upgrade the product on all supported operating systems. The downloaded executable file steps you through the upgrade process and sets your upgrade parameters.

Procedure

Download the installation file for your environment. Installation files are available in two locations.
Location 1: Visit the FlexNet download center and select the file for your environment.
Location 2:
Download the installation file for your environment.
Run the downloaded executable file.

Note: For macOS and Linux installations, set the appropriate permissions before running the file: sudo chmod +x.

Note: HCL™ Accelerate does not perform malware scanning on the installed files. It is recommended that end users implement malware scanning as appropriate for their environment before installing and running the HCL™ Accelerate in their environment.
Complete installation by responding to the prompts described in the following steps:
When the script starts, you are prompted to accept the license. You can explicitly accept the license without viewing it by appending the following parameter to the command:
```
./<Accelerate-installation-file>--license=accept
```
1. At the Please enter your HCL Accelerate access key prompt, accept the default value.
  The default value is the key you entered when you installed the product. If you are upgrading from the Community Edition, enter your new Standard Edition key.
2. At the Enter your encryption key or leave blank to use the default. Key must be at least 8 characters prompt, enter your encryption key or leave blank to use the default encryption key.
  
  Note: The encryption key must be at least 8 characters. Save the encryption key to use for further upgrades.
3. At the Choose the platform prompt, select Docker Compose (Evaluation only).
4. At the Enter the location where the HCL Accelerate files will be installed prompt, enter the location where you want to install the product files.
  You do not have to use the location that you used when you installed the product.
  
  Files are copied to the specified directory in a subdirectory named product_version_number.
5. At the Enter path to the folder containing your "server.crt" and "server.key" files or leave blank to use default prompt, enter the location where you saved the server.crt and server.key certificate files or leave blank to use the default folder.
6. At the Please enter the hostname where you will run HCL Accelerate prompt, enter the host name where users can access the Web UI.
  The default hostname is the value that you used the last time you used the installer.
7. At the Enter the desired port where HCL Accelerate will run prompt, enter the port number for the Web UI.
  The default port is the value that you used the last time you used the installer.
8. (Applicable for Offline installation only) At the Enter the URL of a remote docker registry to push images, otherwise leave blank prompt, specify one of the following options.
  1. (Default) Local File System: Copy images to the file system and manually load them into the local Docker registry.
  2. Local Docker Registry: Load images into the local Docker registry. This requires the Docker client on the host where the installation script is running.
  3. Remote Docker Registry: Load images into the local Docker registry, and then tag the images and push them to a remote Docker registry. This requires the Docker client on the host where the installation script is running. The images are loaded on the local host.
HCL™ Accelerate is installed successfully.
Run the server by changing to the directory where you installed the product, and start Docker Compose. For example:
```
[installation folder] docker-compose up -d
```
If you replaced the original certificate with your own version, copy it to the [installation folder]product_version_number/conf/ssl folder.
Test the upgrade by changing to the directory where you installed the product, [installation folder]product_version_number and start Docker Compose. For example:
```
[installation folder]1.2.4 docker-compose up -d
```
Access the HCL™ Accelerate Web UI. The URL is https://hostname:port, where hostname and port are the values that you set during upgrade.

What to do next

Advanced usage

Migrate overrides file

If you use an override.yml file, copy it from the original installation directory to the [installation folder]product_version_number/ folder. Restart HCL™ Accelerate for the changes to take effect.

Migrate SSL certificates

If you replaced the original certificate with your own version, copy it to the [installation folder]product_version_number/conf/ssl folder. Restart HCL™ Accelerate for the changes to take effect.
