This article is intended for java developers who need to quickly publish their products to sonatype and/or maven central repositories using GitLab. In this article, I will talk about setting up gitlab-runner, gitlab-ci and maven-plugin to solve this problem.
Prerequisites:
- Safe storage of mvn and GPG keys.
- Secure execution of public CI tasks.
- Uploading artifacts (release/snapshot) to public repositories.
- Automatic check of release versions for publication in maven central.
- A general solution for uploading artifacts to a repository for multiple projects.
- Simplicity and ease of use.
Content
General information
- A detailed description of the mechanism for publishing artifacts to Maven Central via the Sonatype OSS Repository Hosting Service is already described in user , so I will refer to this article in the right places.
- Pre-register at and start a ticket to open the repository (for more details, read the section ). After opening the repository, the JIRA login/password pair (hereinafter referred to as the Sonatype account) will be used to upload artifacts to the Sonatype nexus.
- Further, the process of generating a GPG key is described very dryly. See the section for more details.
- If you are using the Linux console to generate a GPG key (gnupg/gnupg2), then you need to install to generate entropy. Otherwise, key generation can take a very long time.
- Storage Services public GPG keys
Setting up a deploy project in GitLab
- First of all, you need to create and configure a project in which the pipeline will be stored for the deployment of artifacts. I called my project simply and uncomplicated -
- After creating the repository, you need to restrict access to change the repository.
Go to the project -> Settings -> Repository -> Protected Branches. We delete all rules and add a single rule with Wildcard * with the right to push and merge only for users with the Maintainers role. This rule will work for all users of both this project and the group to which this project belongs.
- If there are several maintainers, then the best solution would be to restrict access to the project in principle.
Go to the project -> Settings -> General -> Visibility, project features, permissions and set Project visibility to Private.
I have a project in public access, since I use my own GitLab Runner and only I have access to modify the repository. Well, actually it is not in my interests to show private information in public pipeline logs. - Tightening the rules for changing the repository
Go to the project -> Settings -> Repository -> Push Rules and set the flags Committer restriction, Check whether author is a GitLab user. I also recommend setting , and set the Reject unsigned commits flag. - Next, you need to configure a trigger to run tasks
Go to project -> Settings -> CI / CD -> Pipeline triggers and create a new trigger-token
This token can be immediately added to the general configuration of variables for a group of projects.
Go to the group -> Settings -> CI / CD -> Variables and add a variableDEPLOY_TOKENwith trigger-token in the value.
GitLab Runner
This section describes the configuration for running tasks on deploy using the native (Specific) and public (Shared) runner.
Specific Runner
I use my own runners, because first of all it's convenient, fast, cheap.
For runner I recommend Linux VDS with 1 CPU, 2 GB RAM, 20 GB HDD. Issue price ~ 3000₽ per year.
My runner
For the runner I took VDS 4 CPU, 4 GB RAM, 50 GB SSD. It cost ~11000₽ and never regretted it.
I have a total of 7 machines. 5 on aruba and 2 on ihor.
So, we have a runner. Now we will set it up.
We go to the machine via SSH and install java, git, maven, gnupg2.
Installing gitlab runner
- Create a new group
runnersudo groupadd runner - Create a directory for the maven cache and assign group rights
runner
You can skip this step if you don't plan to run multiple runners on the same machine.mkdir -p /usr/cache/.m2/repository chown -R :runner /usr/cache chmod -R 770 /usr/cache - Create a user
gitlab-deployerand add to the grouprunneruseradd -m -d /home/gitlab-deployer gitlab-deployer usermod -a -G runner gitlab-deployer - Add to file
/etc/ssh/sshd_confignext lineAllowUsers root@* gitlab-deployer@127.0.0.1 - Reboot
sshdsystemctl restart sshd - Set a password for the user
gitlab-deployer(it can be simple, since there is a restriction for localhost)passwd gitlab-deployer - Install GitLab Runner (Linux x86-64)
sudo wget -O /usr/local/bin/gitlab-runner https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-amd64 sudo chmod +x /usr/local/bin/gitlab-runner ln -s /usr/local/bin/gitlab-runner /etc/alternatives/gitlab-runner ln -s /etc/alternatives/gitlab-runner /usr/bin/gitlab-runner - Go to gitlab.com -> deploy-project -> Settings -> CI/CD -> Runners -> Specific Runners and copy the registration token
Screen

Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded!- Check that the runner is registered. Go to gitlab.com -> deploy-project -> Settings -> CI/CD -> Runners -> Specific Runners -> Runners activated for this project
Screen
- Add separate service
/etc/systemd/system/gitlab-deployer.service[Unit] Description=GitLab Deploy Runner After=syslog.target network.target ConditionFileIsExecutable=/usr/local/bin/gitlab-runner [Service] StartLimitInterval=5 StartLimitBurst=10 ExecStart=/usr/local/bin/gitlab-runner "run" "--working-directory" "/home/gitlab-deployer" "--config" "/etc/gitlab-runner/gitlab-deployer-config.toml" "--service" "gitlab-deployer" "--syslog" "--user" "gitlab-deployer" Restart=always RestartSec=120 [Install] WantedBy=multi-user.target - We start the service.
systemctl enable gitlab-deployer.service systemctl start gitlab-deployer.service systemctl status gitlab-deployer.service - Check that the runner is running.
Example
GPG key generation
- From the same machine we go via ssh under the user
gitlab-deployer(this is important for GPG key generation)ssh gitlab-deployer@127.0.0.1 - We generate a key by answering questions. I used my own name and email.
Be sure to specify the password for the key. Artifacts will be signed with this key.gpg --gen-key - Checking
gpg --list-keys -a /home/gitlab-deployer/.gnupg/pubring.gpg ---------------------------------------- pub 4096R/00000000 2019-04-19 uid Petruha Petrov <pp@example.com> sub 4096R/11111111 2019-04-19 - Uploading our public key to the keyserver
gpg --keyserver keys.gnupg.net --send-key 00000000 gpg: sending key 00000000 to hkp server keys.gnupg.net
Maven setup
- We go under the user
gitlab-deployersu gitlab-deployer - Create a maven directory Repository and link with the cache (make no mistake)
This step can be skipped if you do not plan to run several runners on the same machine.mkdir -p ~/.m2/repository ln -s /usr/cache/.m2/repository /home/gitlab-deployer/.m2/repository - Create a master key
mvn --encrypt-master-password password {hnkle5BJ9HUHUMP+CXfGBl8dScfFci/mpsur/73tR2I=} - Create file ~/.m2/settings-security.xml
<settingsSecurity> <master>{hnkle5BJ9HUHUMP+CXfGBl8dScfFci/mpsur/73tR2I=}</master> </settingsSecurity> - Encrypting the password from the Sonatype account
mvn --encrypt-password SONATYPE_PASSWORD {98Wv5+u+Tn0HX2z5G/kR4R8Z0WBgcDBgi7d12S/un+SCU7uxzaZGGmJ8Cu9pAZ2J} - Create file ~/.m2/settings.xml

Where,
GPG_SECRET_KEY_PASSPHRASE - GPG key password
SONATYPE_USERNAME - sonatype account login
This completes the runner setup, you can proceed to the section
Shared Runner
GPG key generation
- First of all, you need to create a GPG key. To do this, install gnupg.
yum install -y gnupg - We generate a key by answering questions. I used my own name and email. Be sure to specify the password for the key.
gpg --gen-key - Retrieve key information
gpg --list-keys -a pub rsa3072 2019-04-24 [SC] [expires: 2021-04-23] 2D0D1706366FC4AEF79669E24D09C55BBA3FD728 uid [ultimate] tttemp <temp@temp.temp> sub rsa3072 2019-04-24 [E] [expires: none] - Uploading our public key to the keyserver
gpg --keyserver keys.gnupg.net --send-key 2D0D1706366FC4AEF79669E24D09C55BBA3FD728 gpg: sending key 2D0D1706366FC4AEF79669E24D09C55BBA3FD728 to hkp server keys.gnupg.net - Getting a private key

GPG_SECRET_KEY
Maven setup
- Create a master key
mvn --encrypt-master-password password {hnkle5BJ9HUHUMP+CXfGBl8dScfFci/mpsur/73tR2I=} - Go to project settings -> Settings -> CI / CD -> Variables and save in a variable
SETTINGS_SECURITY_XMLthe following lines:<settingsSecurity> <master>{hnkle5BJ9HUHUMP+CXfGBl8dScfFci/mpsur/73tR2I=}</master> </settingsSecurity> - Encrypting the password from the Sonatype account
mvn --encrypt-password SONATYPE_PASSWORD {98Wv5+u+Tn0HX2z5G/kR4R8Z0WBgcDBgi7d12S/un+SCU7uxzaZGGmJ8Cu9pAZ2J} - Go to project settings -> Settings -> CI / CD -> Variables and save in a variable

Where,
GPG_SECRET_KEY_PASSPHRASE - GPG key password
SONATYPE_USERNAME - sonatype account login
Deploy docker image
- We create a fairly simple Dockerfile to run tasks on deploy with the desired version of Java. Below is an example for alpine.
FROM java:8u111-jdk-alpine RUN apk add gnupg maven git --update-cache --repository http://dl-4.alpinelinux.org/alpine/edge/community/ --allow-untrusted && mkdir ~/.m2/ - Building a container for your project
docker build -t registry.gitlab.com/group/deploy . - We authenticate and load the container into the registry.
docker login -u USER -p PASSWORD registry.gitlab.com docker push registry.gitlab.com/group/deploy
GitLab CI
Deploy project
Add the file .gitlab-ci.yml to the root of the deploy project
The script presents two mutually exclusive deployment tasks. Specific Runner or Shared Runner respectively.

This topic is described in great detail. в , so I will describe some of the nuances of using plugins. I will also describe how easily and naturally you can use nexus-staging-maven-pluginif you don't want or can't use org.sonatype.oss:oss-parent as the parent for your project.
maven-install-plugin

Publication of the release version
When the tag is set, the corresponding task in the deploy project is automatically triggered to upload the release version to nexus ().
The best part is that close release automatically triggers in nexus.

It was a revelation to me that maven indexes other public repositories.
I had to upload robots.txt because it indexed my old repository.
Conclusion
What we have
- A separate deploy project in which you can implement several CI tasks for uploading artifacts to public repositories for various development languages.
- The deployment project is isolated from outside interference and can only be modified by users with the Owner and Maintainer roles.
- A separate Specific Runner with a "hot" cache to run only deploy tasks.
- Publication of snapshot/release versions in a public repository.
- Automatic check of the release version for readiness for publication in maven central.
- Protection against automatic publication of "raw" versions in maven central.
- Build and publish snapshot versions on click.
- Single repository for getting snapshot/release versions.
- General pipeline for building / testing / publishing a java project.
Setting up GitLab CI is not such a complicated topic as it seems at first glance. It is enough to set up CI on a turnkey basis a couple of times, and now, you are far from being an amateur in this matter. Moreover, GitLab documentation is very redundant. Don't be afraid to take the first step. The road appears under the steps of the walker (I don’t remember who said 🙂).
I will be glad to feedback.
In the next article, I'll show you how to set up GitLab CI to run integration test tasks competitively (running test services with docker-compose) if you only have one shell runner.
