Steps to reproduce
- Create a container with the following command:
docker run --rm --cap-add net_admin -d nginx - Compile and run the following java code:
import com.github.dockerjava.api.DockerClient; import com.github.dockerjava.core.*; import com.github.dockerjava.httpclient5.ApacheDockerHttpClient; import com.github.dockerjava.transport.DockerHttpClient; import java.net.URI; public class DockerTest { public static void main(String[] args) { DockerClientConfig config = DefaultDockerClientConfig.createDefaultConfigBuilder() .withDockerHost("unix:///var/run/docker.sock") .withDockerTlsVerify(false) .withApiVersion(RemoteApiVersion.VERSION_1_42) .build(); DockerHttpClient httpClient = new ApacheDockerHttpClient.Builder() .dockerHost(URI.create("unix:///var/run/docker.sock")) .build(); DockerClient client = DockerClientImpl.getInstance(config, httpClient); client.inspectContainerCmd("<container_id>").exec(); // replace this with actual container id } } - The following exception is thrown:
Exception in thread "main" java.lang.RuntimeException: com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot deserialize value of type `com.github.dockerjava.api.model.Capability` from String "net_admin": not one of the values accepted for Enum class: [ALL, SYS_BOOT, DAC_OVERRIDE, NET_RAW, BLOCK_SUSPEND, FOWNER, IPC_LOCK, IPC_OWNER, SYS_PACCT, NET_BIND_SERVICE, WAKE_ALARM, FSETID, DAC_READ_SEARCH, SYS_CHROOT, AUDIT_READ, SYS_RAWIO, SYS_ADMIN, KILL, MAC_ADMIN, SYS_RESOURCE, CHOWN, PERFMON, SETPCAP, SYS_PTRACE, NET_ADMIN, SETFCAP, SYS_NICE, LINUX_IMMUTABLE, BPF, AUDIT_CONTROL, LEASE, AUDIT_WRITE, SYS_MODULE, MKNOD, SYSLOG, MAC_OVERRIDE, SYS_TIME, SETGID, SETUID, CHECKPOINT_RESTORE, SYS_TTY_CONFIG, NET_BROADCAST] at [Source: UNKNOWN; byte offset: #UNKNOWN] (through reference chain: com.github.dockerjava.api.command.InspectContainerResponse["HostConfig"]->com.github.dockerjava.api.model.HostConfig["CapAdd"]->java.lang.Object[][0]) at com.github.dockerjava.core.DefaultInvocationBuilder.get(DefaultInvocationBuilder.java:77) at com.github.dockerjava.core.exec.InspectContainerCmdExec.execute(InspectContainerCmdExec.java:31) at com.github.dockerjava.core.exec.InspectContainerCmdExec.execute(InspectContainerCmdExec.java:13) at com.github.dockerjava.core.exec.AbstrSyncDockerCmdExec.exec(AbstrSyncDockerCmdExec.java:21) at com.github.dockerjava.core.command.AbstrDockerCmd.exec(AbstrDockerCmd.java:33) at com.github.dockerjava.core.command.InspectContainerCmdImpl.exec(InspectContainerCmdImpl.java:51) at dockerbug.DockerTest.main(DockerTest.java:24) - Start another container with the following:
docker run --rm --cap-add NET_ADMIN -d nginx - Run the java program again with the new id from step 5, and now it runs without error.
- Same issue is seen using
--cap-drop net_admin
