org.aksw.shellgebra.processbuilder.ProcessBuilderDockerExec
All Implemented Interfaces:
Cloneable, IProcessBuilder<ProcessBuilderDockerExec>, IProcessBuilderCore<ProcessBuilderDockerExec>
public class ProcessBuilderDockerExec extends ProcessBuilderBase<ProcessBuilderDockerExec>
Process builder to execute commands in a running container via docker exec. This is a limited form of execution because bind mounts cannot by dynamically altered.

      public ProcessBuilderDockerExec(org.testcontainers.containers.GenericContainer<?> container)

  • Method Details

    • supportsAnonPipeRead

      public boolean supportsAnonPipeRead()
      Description copied from interface: IProcessBuilderCore
      Whether the process builder can read from anonymous pipes. Docker containers can only bind-mount named pipes but not anonymous pipes. When building pipelines, this flag is used to avoid needless intermediate anon pipes where named ones can be used directly. For pipelines, this is the value of the first process builder.

    • supportsAnonPipeWrite

      public boolean supportsAnonPipeWrite()
      Description copied from interface: IProcessBuilderCore
      Whether the process builder can write to an anonymous pipe. Docker containers can only bind-mount named pipes but not anonymous pipes. When building pipelines, this flag is used to avoid needless intermediate anon pipes where named ones can be used directly. For pipelines, this is the value of the last process builder.

    • supportsDirectNamedPipe

      public boolean supportsDirectNamedPipe()
      Description copied from interface: IProcessBuilderCore
      Whether a named pipe can be used with the process builder without risking blocking due to multiple connections being made to it. This method must only return true if only a single connection to that pipe will be openend. A process builder for host or docker may return true. But a group with two or more 'true-returning' members will return false.

    • accessesStdIn

      public boolean accessesStdIn()
      Description copied from interface: IProcessBuilderCore
      Whether the configured command will read from stdin. Used to avoid generation of needless named or anon pipes such as in "echo foo | echo bar": where the second link does not read the data from the prior link.
