Conan packages in the package registry All tiers All offerings Experiment
- Introduced in GitLab 12.6.
- Moved from GitLab Premium to GitLab Free in 13.3.
Publish Conan packages in your project’s package registry. Then install the packages whenever you need to use them as a dependency.
To publish Conan packages to the package registry, add the package registry as a remote and authenticate with it.
Then you can run conan
commands and publish your package to the
package registry.
For documentation of the specific API endpoints that the Conan package manager client uses, see the Conan API documentation.
Learn how to build a Conan package.
Add the package registry as a Conan remote
To run conan
commands, you must add the package registry as a Conan remote for
your project or instance. Then you can publish packages to
and install packages from the package registry.
Add a remote for your project
Introduced in GitLab 13.4.
Set a remote so you can work with packages in a project without having to specify the remote name in every command.
When you set a remote for a project, there are no restrictions to your package names.
However, your commands must include the full recipe, including the user and channel,
for example, package_name/version@user/channel
.
To add the remote:
-
In your terminal, run this command:
conan remote add gitlab https://gitlab.example.com/api/v4/projects/<project_id>/packages/conan
-
Use the remote by adding
--remote=gitlab
to the end of your Conan command.For example:
conan search Hello* --remote=gitlab
Add a remote for your instance
Use a single remote to access packages across your entire GitLab instance.
However, when using this remote, you must follow these package naming restrictions.
To add the remote:
-
In your terminal, run this command:
conan remote add gitlab https://gitlab.example.com/api/v4/packages/conan
-
Use the remote by adding
--remote=gitlab
to the end of your Conan command.For example:
conan search 'Hello*' --remote=gitlab
Package recipe naming convention for instance remotes
The standard Conan recipe convention is package_name/version@user/channel
, but
if you’re using an instance remote, the
recipe user
must be the plus sign (+
) separated project path.
Example recipe names:
Project | Package | Supported |
---|---|---|
foo/bar
| my-package/1.0.0@foo+bar/stable
| Yes |
foo/bar-baz/buz
| my-package/1.0.0@foo+bar-baz+buz/stable
| Yes |
gitlab-org/gitlab-ce
| my-package/1.0.0@gitlab-org+gitlab-ce/stable
| Yes |
gitlab-org/gitlab-ce
| my-package/1.0.0@foo/stable
| No |
Project remotes have a more flexible naming convention.
Authenticate to the package registry
GitLab requires authentication to upload packages, and to install packages from private and internal projects. (You can, however, install packages from public projects without authentication.)
To authenticate to the package registry, you need one of the following:
- A personal access token
with the scope set to
api
. - A deploy token with the
scope set to
read_package_registry
,write_package_registry
, or both. - A CI job token.
unable to find the package in remote
in the Conan client.Add your credentials to the GitLab remote
Associate your token with the GitLab remote, so that you don’t have to explicitly add a token to every Conan command.
Prerequisites:
- You must have an authentication token.
- The Conan remote must be configured.
In a terminal, run this command. In this example, the remote name is gitlab
.
Use the name of your remote.
conan user <gitlab_username or deploy_token_username> -r gitlab -p <personal_access_token or deploy_token>
Now when you run commands with --remote=gitlab
, your username and password are
included in the requests.
Set a default remote for your project (optional)
If you want to interact with the GitLab package registry without having to specify a remote, you can tell Conan to always use the package registry for your packages.
In a terminal, run this command:
conan remote add_ref Hello/0.1@mycompany/beta gitlab
Hello/0.1@user/channel
doesn’t work for Hello/0.2@user/channel
.If you don’t set a default user or remote, you can still include the user and remote in your commands:
`CONAN_LOGIN_USERNAME=<gitlab_username or deploy_token_username> CONAN_PASSWORD=<personal_access_token or deploy_token> <conan command> --remote=gitlab
Publish a Conan package
Publish a Conan package to the package registry, so that anyone who can access the project can use the package as a dependency.
Prerequisites:
- The Conan remote must be configured.
- Authentication with the package registry must be configured.
- A local Conan package
must exist.
- For an instance remote, the package must meet the naming convention.
- You must have the project ID, which is on the project’s homepage.
To publish the package, use the conan upload
command:
conan upload Hello/0.1@mycompany/beta --all
Publish a Conan package by using CI/CD
- Introduced in GitLab 12.7.
- Moved from GitLab Premium to GitLab Free in 13.3.
To work with Conan commands in GitLab CI/CD, you can
use CI_JOB_TOKEN
in place of the personal access token in your commands.
You can provide the CONAN_LOGIN_USERNAME
and CONAN_PASSWORD
with each Conan
command in your .gitlab-ci.yml
file. For example:
image: conanio/gcc7
create_package:
stage: deploy
script:
- conan remote add gitlab ${CI_API_V4_URL}/projects/$CI_PROJECT_ID/packages/conan
- conan new <package-name>/0.1 -t
- conan create . <group-name>+<project-name>/stable
- CONAN_LOGIN_USERNAME=ci_user CONAN_PASSWORD=${CI_JOB_TOKEN} conan upload <package-name>/0.1@<group-name>+<project-name>/stable --all --remote=gitlab
environment: production
Additional Conan images to use as the basis of your CI file are available in the Conan docs.
Re-publishing a package with the same recipe
When you publish a package that has the same recipe (package-name/version@user/channel
)
as an existing package, the duplicate files are uploaded successfully and
are accessible through the UI. However, when the package is installed,
only the most recently-published package is returned.
Install a Conan package
Install a Conan package from the package registry so you can use it as a dependency. You can install a package from the scope of your instance or your project. If multiple packages have the same recipe, when you install a package, the most recently-published package is retrieved.
Conan packages are often installed as dependencies by using the conanfile.txt
file.
Prerequisites:
- The Conan remote must be configured.
- For private and internal projects, you must configure Authentication with the package registry.
-
In the project where you want to install the package as a dependency, open
conanfile.txt
. Or, in the root of your project, create a file calledconanfile.txt
. -
Add the Conan recipe to the
[requires]
section of the file:[requires] Hello/0.1@mycompany/beta [generators] cmake
-
At the root of your project, create a
build
directory and change to that directory:mkdir build && cd build
-
Install the dependencies listed in
conanfile.txt
:conan install .. <options>
~/.conan/data
to clean up the packages stored in the cache.Remove a Conan package
There are two ways to remove a Conan package from the GitLab package registry.
-
From the command line, using the Conan client:
conan remove Hello/0.2@user/channel --remote=gitlab
You must explicitly include the remote in this command, otherwise the package is removed only from your local system cache.
This command removes all recipe and binary package files from the package registry. -
From the GitLab user interface:
Go to your project’s Deploy > Package Registry. Remove the package by selecting Remove repository ().
Search for Conan packages in the package registry
To search by full or partial package name, or by exact recipe, run the
conan search
command.
-
To search for all packages with a specific package name:
conan search Hello --remote=gitlab
-
To search for a partial name, like all packages starting with
He
:conan search He* --remote=gitlab
The scope of your search depends on your Conan remote configuration:
-
If you have a remote configured for your instance, your search includes all projects you have permission to access. This includes your private projects as well as all public projects.
-
If you have a remote configured for a project, your search includes all packages in the target project, as long as you have permission to access it.
Fetch Conan package information from the package registry
The conan info
command returns information about a package:
conan info Hello/0.1@mycompany/beta
Supported CLI commands
The GitLab Conan repository supports the following Conan CLI commands:
-
conan upload
: Upload your recipe and package files to the package registry. -
conan install
: Install a Conan package from the package registry, which includes using theconanfile.txt
file. -
conan search
: Search the package registry for public packages, and private packages you have permission to view. -
conan info
: View the information on a given package from the package registry. -
conan remove
: Delete the package from the package registry.
Troubleshooting
Make output verbose
For more verbose output when troubleshooting a Conan issue:
export CONAN_TRACE_FILE=/tmp/conan_trace.log # Or SET in windows
conan <command>
You can find more logging tips in the Conan documentation.
SSL Errors
If you are using a self-signed certificate, there are two methods to manage SSL errors with Conan:
- Use the
conan remote
command to disable the SSL verification. - Append your server
crt
file to thecacert.pem
file.
