Test documentation changes
Every project keeps technical documentation that’s published to the website in the docs/sources
directory.
That documentation is published to the content/docs
directory in the website repository.
Additionally, every project uses GNU Make to perform tasks related to technical documentation. To learn more about GNU Make, refer to GNU Make Manual.
To see a list of targets and their descriptions, run make help
from the docs/
directory.
If you are in the website repository, run make help
from the root of the repository instead.
The output is similar to the following:
Usage:
make <target>
Targets:
help Display this help.
docs-rm Remove the docs container.
docs-pull Pull documentation base image.
make-docs Fetch the latest make-docs script.
docs Serve documentation locally, which includes pulling the latest `DOCS_IMAGE` (default: `grafana/docs-base:latest`) container image. To not pull the image, set `PULL=false`.
docs-debug Run Hugo web server with debugging enabled. TODO: support all SERVER_FLAGS defined in website Makefile.
doc-validator Run doc-validator on the entire docs folder which includes pulling the latest `DOC_VALIDATOR_IMAGE` (default: `grafana/doc-validator:latest`) container image. To not pull the image, set `PULL=false`.
vale Run vale on the entire docs folder which includes pulling the latest `VALE_IMAGE` (default: `grafana/vale:latest`) container image. To not pull the image, set `PULL=false`.
update Fetch the latest version of this Makefile and the `make-docs` script from Writers' Toolkit.
To run the local documentation web server, run make docs
from the docs/
directory.
If you are in the website repository, run make docs
from the root of the repository instead.
Note
Runningmake docs
from the wrong directory, produces the outputmake: Nothing to be done for 'docs'.
ormake: *** No rule to make target 'docs'. Stop.
, and the local documentation web server is not started. To run the local documentation web server, ensure that you are in the right directory.
The output message of a successful build includes a URL that you can follow to view the changes to the documentation in the browser. Refer to an example of a successful build.
Run with specific projects
Each repository has a list of projects to build by default when running make docs
, defined by the PROJECTS
variable in docs/variables.mk
.
To override the defaults, provide the PROJECTS
option to make docs
.
The argument is a space-separated list of names of the projects.
The project name for a repository is the sub-directory of the /docs/
directory in the website where the repository publishes documentation.
For example:
- For Grafana, the
PROJECT
isgrafana
derived the URLhttps://grafana.com/docs/grafana/
. - For Grafana Cloud, the
PROJECT
isgrafana-cloud
derived from the URLhttps://grafana.com/docs/grafana-cloud/
.
Note
You must have the repository cloned locally for any projects specified in the space separated list toPROJECTS
for the command to succeed.
To build only the Grafana documentation:
make docs PROJECTS=grafana
To build Grafana and Grafana Cloud documentation:
make docs 'PROJECTS=grafana grafana-cloud'
If your local repository name doesn’t match the upstream repository name.
You can use the PROJECTS
option to override the directory.
For example, if you have the Tempo repository tempo
cloned into a directory called tempo-doc-work
.
make docs PROJECTS=tempo::tempo-doc-work
The format is <PROJECT>[:VERSION[:REPOSITORY[:DIRECTORY]]].
The example mounts the PROJECT
tempo
, at the default VERSION
(since the VERSION
argument is empty), using the REPOSITORY
tempo-doc-work
, and the default documentation DIRECTORY
docs/sources
.
This example builds the Tempo documentation from the local working directory, tempo-doc-work
, instead of the standard tempo
directory.
Understand Hugo output from make docs
When you run make docs
, Hugo renders the Markdown files and outputs warnings and error messages.
These messages are in the following format:
<LEVEL> [LANGUAGE] <MESSAGE>
where:
<LEVEL>
is one ofWARN
orERROR
<LANGUAGE>
may be present<MESSAGE>
is the issue
Example: Successful build
If the make docs
command runs correctly, the console prints a message similar to the following:
View documentation locally:
http://localhost:3002/docs/grafana/latest/
Press Ctrl+C to stop the server
Note
To test Grafana tutorial changes, the address ishttp://localhost:3002/docs/grafana/latest/tutorials/
.
Example: Page not found
Hugo emits REF_NOT_FOUND
warnings indicating the filename and location of such references when building the docs, for example with make docs
in grafana/grafana
or make server-quick
in grafana/website
:
WARN 2022/08/04 21:35:37 [en] REF_NOT_FOUND: Ref "../../enterprise": "/hugo/content/docs/grafana/next/administration/roles-and-permissions/access-control/assign-rbac-roles.md:14:47": page not found
In this example,
Ref "../../enterprise"
is the destination of the reference that Hugo can’t resolve\/hugo/content/docs/grafana/next/administration/roles-and-permissions/access-control/assign-rbac-roles.md
is the document containing the reference, where the path after/next/
is relative to the documentation root of the component repository:14
represents the line number containing the unresolved reference:47
represents the character in that line where the unresolved reference begins
If you see this error, then the reference’s destination is invalid. This may be due to a typo in the reference or having the incorrect path to the destination directory. Fix the error by correcting the reference target.
For more information about linking, refer to Links.
Example: Rebuild failed due to missing shortcode
In this example, the rebuild fails because the file contribute-documentation/_index.md
is missing a closing shortcode for admonition
on line 152.
ERROR Rebuild failed: assemble: "/hugo/content/docs/writers-toolkit/contribute-documentation/_index.md:152:1": failed to extract shortcode: shortcode "admonition" must be closed or self-closed
Extended usage
Refer to the following sections for examples of more complicated usage of make docs
.
Mount documentation to a different version
make docs PROJECTS=grafana:next
Mount v9.3.x
and the default version of Grafana documentation together
Run the following command from the root of the repository to add a worktree that contains the v9.3.x
branch:
git worktree add v9.3.x origin/v9.3.x
Change to the docs/
directory:
cd docs
Run make docs
with both versions:
make docs 'PROJECTS=grafana grafana:v9.3.x:grafana'
To remove the worktree, run the following command from the root of the repository:
git worktree remove v9.3.x
Arguments
Each argument to the make-docs
script is a project to be mounted into the local build.
Each argument has four fields separated by colons (:
), and optional fields can be omitted.
<PROJECT>[:VERSION[:REPOSITORY[:DIRECTORY]]]
<PROJECT>
: is the sub-directory of the/docs/
directory in the website where the repository publishes documentation.For example:
- For Grafana,
<PROJECT>
isgrafana
(https://grafana.com/docs/grafana/
) - For Grafana Cloud,
<PROJECT>
isgrafana-cloud
(https://grafana.com/docs/grafana-cloud/
).
Pseudo projects mount multiple source directories.
logs
: mounts Loki and Grafana Enterprise Logs (GEL) directories.metrics
: mounts Mimir, themimir-distributed
Helm chart, and Grafana Enterprise Metrics (GEM) directories.traces
: mounts Tempo and Grafana Enterprise Traces (GET) directories.
Note
Pseudo projects don’t support the<REPOSITORY>
or<DIR>
fields.- For Grafana,
<VERSION>
: is the name of the version directory to mount the documentation in.The
<VERSION>
field is optional and defaults tolatest
for versioned projects and is empty for other projects.<REPOSITORY>
: is the name of the directory that the project is cloned to.The
<REPOSITORY>
field is optional and defaults to the script’s internal mapping of project names to repository names. For most projects, this is the same as the project name.<DIRECTORY>
: is the directory path within the repository containing the technical documentation documentation.The
<DIRECTORY>
field is optional and defaults to the script’s internal mapping of project names to documentation source directories. For most projects, it’s thedocs/sources
directory.
REPOS_PATH
The REPOS_PATH
environment variable is a colon-separated list of paths in which to look for project repositories.
The script only checks for projects in the directories specified in REPOS_PATH
.
By default, the script determines the REPOS_PATH
to be the parent directory of the current project.
If you keep all repositories in the same directory, you don’t need to set REPOS_PATH
.
With a directory structure similar to the following output from the tree -L 1 -d ~/ext/grafana
command:
/home/username/ext/grafana
├── agent
├── grafana
├── loki
├── mimir
├── phlare
├── technical-documentation
├── tempo
├── website
└── writers-toolkit
9 directories
When you run make docs
from the Grafana repository, the script sets REPOS_PATH
to be /home/username/ext/grafana
.
DEBUG
The DEBUG
environment variable disables output filtering and enables extra debug logging to help with troubleshooting.
If you experience confusing behavior with the make docs
procedure, report the problem via a GitHub issue or, for Grafana Labs employees, in the #docs Slack channel and provide the full command and output using make docs DEBUG=true
.
Stop running a local build
To stop the make docs
command, press Commmand/Ctrl + C.
Sometimes an old build process can be running in another terminal.
If this is the case, when you run make docs
, you see output similar to the following:
docker: Error response from daemon: driver failed programming external connectivity on endpoint eloquent_nightingale (eb2c4546727b41bbc44354ac616a14404c57f30c312f6869b147c578ac5de6bf): Bind for 0.0.0.0:3002 failed: port is already allocated.
make: *** [docs] Error 125
To remove an old build process, do one of the following:
- Open Docker Desktop, go to Containers, and stop all running containers or just the one for your local build.
- To remove all running containers, run
docker rm -f $(docker ps -q)
.
