Cases when GitLab CI/CD does not work

1. Unsupported Programming Languages: GitLab CI/CD may not work with certain programming languages that are not supported by default. While GitLab CI/CD supports a wide range of popular programming languages such as Python, Java, Ruby, and Go, there might be cases where less common or niche programming languages are not directly supported. In such cases, additional configuration and custom scripting may be required to enable CI/CD pipelines for these languages.
2. Complex Build Environments: GitLab CI/CD relies on Docker containers to provide a consistent and isolated build environment for running pipelines. However, certain complex build environments that require specialized hardware or software configurations may not be easily reproducible within a Docker container. For example, if your project requires access to specific GPU resources or specialized hardware devices, GitLab CI/CD might not be the optimal choice for your CI/CD needs.
3. Limited Scalability: While GitLab CI/CD is capable of handling a large number of concurrent pipelines, there might be cases where extremely high scalability requirements cannot be met. For organizations with massive workloads and stringent performance demands, alternative CI/CD solutions specifically designed for high scalability might be more suitable.
4. Network Restrictions: GitLab CI/CD heavily relies on network connectivity to access code repositories, perform builds, and deploy artifacts. If your organization has strict network restrictions or firewalls that block access to external resources or limit the outbound connections from CI/CD runners, it may hinder the proper functioning of GitLab CI/CD pipelines.
5. Complex Deployment Scenarios: GitLab CI/CD provides a robust set of deployment options, including Kubernetes, AWS, and Google Cloud, among others. However, in some complex deployment scenarios that require highly customized deployment processes or integration with legacy systems, GitLab CI/CD may not offer out-of-the-box solutions. In such cases, additional scripting and customization might be necessary to achieve the desired deployment workflow.
