# Building a container image

## Prerequisites

You need to have the following tools installed:

* [Docker](https://www.docker.com/) 20.10 or later, or [Podman](https://podman.io) 4.4 or later.
* [GNU make](https://www.gnu.org/software/make/)

## Building Images

To build an IBM MQ image, navigate to the appropriate section:

- [Building a production image](#building-a-production-image)
- [Building a developer image](#building-a-developer-image)

## Building a production image

### MQ Continuous Delivery (CD)

The procedure below is for building the 9.4.1 release, on `amd64`, `ppc64le` and `s390x` architectures.

1. Create a `downloads` directory in the root of this repository
2. Identify the correct eImage part number for your architecture from https://www.ibm.com/support/pages/downloading-ibm-mq-94 and download
3. Ensure the `tar.gz` file is in the `downloads` directory
4. Run `make build-advancedserver`

If you have an MQ archive file with a different file name, you can specify a particular file (which must be in the `downloads` directory).  You should also specify the MQ version, so that the resulting image is tagged correctly, for example:

```bash
MQ_ARCHIVE=mq-1.2.3.4.tar.gz MQ_VERSION=1.2.3.4 make build-advancedserver
```

### MQ LTS

The procedure below is for building the 9.4.0 release, on `amd64`, `ppc64le` and `s390x` architectures.

1. Create a `downloads` directory in the root of this repository
2. Identify the correct eImage part number for your architecture from https://www.ibm.com/support/pages/downloading-ibm-mq-94 and download
3. Ensure the `tar.gz` file is in the `downloads` directory
4. Run `make build-advancedserver`

If you have an MQ archive file with a different file name, you can specify a particular file (which must be in the `downloads` directory).  You should also specify the MQ version, so that the resulting image is tagged correctly, for example:

```bash
MQ_ARCHIVE=mq-1.2.3.4.tar.gz MQ_VERSION=1.2.3.4 make build-advancedserver
```

## Building a developer image

Run `make build-devserver`, which will download the latest version of MQ Advanced for Developers.  This is available on the `amd64` and `arm64` (Apple Silicon) architectures.

You can use the environment variable `MQ_ARCHIVE_DEV` to specify an alternative local file to install from (which must be in the `downloads` directory).

## Installed components

This image includes the core MQ server, Java, language packs, GSKit, and web server.  This is configured in the `mq-redux` build stage in `Dockerfile-server`.
