Since CentOS 8 will be EOL at the end of the year it makes sense to do this now. The centos:8 image is still used in documentation.xml because changes there require manual testing, which will need to be done at a later date. The changes are not user-facing, however, and can be done at any time. Also update CentOS references to RHEL since that is what we are emulating for testing purposes.

<p>The <backrest/> documentation can output a variety of formats and target several platforms and <postgres/> versions.</p>
|
|
|
|
<p>This will build all documentation with defaults:</p>
|
|
|
|
<code-block type="bash">
|
|
./doc.pl
|
|
</code-block>
|
|
|
|
<p>The user guide can be built for <id>rhel</id> and <id>debian</id>. This will build the HTML user guide for RHEL:</p>
|
|
|
|
<code-block type="bash">
|
|
./doc.pl --out=html --include=user-guide --var=os-type=rhel
|
|
</code-block>
|
|
|
|
<p>Documentation generation will build a cache of all executed statements and use the cache to build the documentation quickly if no executed statements have changed. This makes proofing text-only edits very fast, but sometimes it is useful to do a full build without using the cache:</p>
|
|
|
|
<code-block type="bash">
|
|
./doc.pl --out=html --include=user-guide --var=os-type=rhel --no-cache
|
|
</code-block>
|
|
|
|
<p>Each <id>os-type</id> has a default container image that will be used as a base for creating hosts but it may be useful to change the image.</p>
|
|
|
|
<code-block type="bash">
|
|
./doc.pl --out=html --include=user-guide --var=os-type=debian --var=os-image=debian:9
|
|
./doc.pl --out=html --include=user-guide --var=os-type=rhel --var=os-image=centos:7
|
|
</code-block>
|

<p>The following is a sample RHEL 7 configuration that can be used for building the documentation.</p>

<title>Building with Packages</title>
|

|
|
<p>A user-specified package can be used when building the documentation. Since the documentation exercises most <backrest/> functionality this is a great way to smoke-test packages.</p>
|
|
|
|
<p>The package must be located within the <backrest/> repo and the specified path should be relative to the repository base. <path>test/package</path> is a good default path to use.</p>

<p>Ubuntu 16.04:</p>
