It is possible to encounter a syntax error in the pattern when checking the context of a Docker build. This can be caused by a missing dependency in the build log, or by incorrect syntax in the .dockerignore or .travis.yml files.
Additionally, permission denied errors can occur when trying to connect to the Docker daemon socket.
The user is having trouble running the docker command in Debian, and is having different results from other Jenkins jobs. After doing a full restart of docker, the user is able to successfully send the build context to the Docker daemon. However, there is an issue with the build-env command, which is not relevant to the original question.
Question : docker command won't run in Debian
Travis CI is a Continuous Integration service used to build and test software, and if a build fails, it is possible to cause a dependency to be missing. To troubleshoot this issue, it is important to check the list of dependencies in the build log, usually output including the.dockerignore file in the root directory of the context, and to use the syntax in the.travis.yml file. Additionally, it is possible to run across build issues during active development, such as permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock.
