Configuration

This configuration file contains metadata necessary to implement standard operations against the container. This includes the process to run, environment variables to inject, sandboxing features to use, etc.

The canonical schema is defined in this document, but there is a JSON Schema in schema/config-schema.json and Go bindings in specs-go/config.go. Platform-specific configuration schema are defined in the platform-specific documents linked below. For properties that are only defined for some platforms, the Go property has a platform tag listing those protocols (e.g. platform:"linux,solaris").

Below is a detailed description of each field defined in the configuration format and valid values are specified. Platform-specific fields are identified as such. For all platform-specific configuration values, the scope defined below in the Platform-specific configuration section applies.

Specification version

  • ociVersion (string, REQUIRED) MUST be in SemVer v2.0.0 format and specifies the version of the Open Container Initiative Runtime Specification with which the bundle complies. The Open Container Initiative Runtime Specification follows semantic versioning and retains forward and backward compatibility within major versions. For example, if a configuration is compliant with version 1.1 of this specification, it is compatible with all runtimes that support any 1.1 or later release of this specification, but is not compatible with a runtime that supports 1.0 and not 1.1.

Example

"ociVersion": "0.1.0"

Root

root (object, OPTIONAL) specifies the container's root filesystem. On Windows, for Windows Server Containers, this field is REQUIRED. For Hyper-V Containers, this field MUST NOT be set.

On all other platforms, this field is REQUIRED.

  • path (string, REQUIRED) Specifies the path to the root filesystem for the container.

    • On Windows, path MUST be a volume GUID path.
    • On POSIX platforms, path is either an absolute path or a relative path to the bundle. For example, with a bundle at /to/bundle and a root filesystem at /to/bundle/rootfs, the path value can be either /to/bundle/rootfs or rootfs. The value SHOULD be the conventional rootfs.

    A directory MUST exist at the path declared by the field.

  • readonly (bool, OPTIONAL) If true then the root filesystem MUST be read-only inside the container, defaults to false.

    • On Windows, this field MUST be omitted or false.

Example (POSIX platforms)

"root": {
    "path": "rootfs",
    "readonly": true
}

Example (Windows)

"root": {
    "path": "\\\\?\\Volume{ec84d99e-3f02-11e7-ac6c-00155d7682cf}\\"
}

Mounts

mounts (array of objects, OPTIONAL) specifies additional mounts beyond root. The runtime MUST mount entries in the listed order. For Linux, the parameters are as documented in mount(2) system call man page. For Solaris, the mount entry corresponds to the 'fs' resource in the zonecfg(1M) man page.

  • destination (string, REQUIRED) Destination of mount point: path inside container. This value MUST be an absolute path.
    • Windows: one mount destination MUST NOT be nested within another mount (e.g., c:\foo and c:\foo\bar).
    • Solaris: corresponds to "dir" of the fs resource in zonecfg(1M).
  • source (string, OPTIONAL) A device name, but can also be a file or directory name for bind mounts or a dummy. Path values for bind mounts are either absolute or relative to the bundle. A mount is a bind mount if it has either bind or rbind in the options.
    • Windows: a local directory on the filesystem of the container host. UNC paths and mapped drives are not supported.
    • Solaris: corresponds to "special" of the fs resource in zonecfg(1M).
  • options (array of strings, OPTIONAL) Mount options of the filesystem to be used.

Example (Windows)

"mounts": [
    {
        "destination": "C:\\folder-inside-container",
        "source": "C:\\folder-on-host",
        "options": ["ro"]
    }
]

POSIX-platform Mounts

For POSIX platforms the mounts structure has the following fields:

Example (Linux)

"mounts": [
    {
        "destination": "/tmp",
        "type": "tmpfs",
        "source": "tmpfs",
        "options": ["nosuid","strictatime","mode=755","size=65536k"]
    },
    {
        "destination": "/data",
        "type": "none",
        "source": "/volumes/testing",
        "options": ["rbind","rw"]
    }
]

Example (Solaris)

"mounts": [
    {
        "destination": "/opt/local",
        "type": "lofs",
        "source": "/usr/local",
        "options": ["ro","nodevices"]
    },
    {
        "destination": "/opt/sfw",
        "type": "lofs",
        "source": "/opt/sfw"
    }
]

Process

process (object, OPTIONAL) specifies the container process. This property is REQUIRED when start is called.

  • terminal (bool, OPTIONAL) specifies whether a terminal is attached to the process, defaults to false. As an example, if set to true on Linux a pseudoterminal pair is allocated for the process and the pseudoterminal pty is duplicated on the process's standard streams.
  • consoleSize (object, OPTIONAL) specifies the console size in characters of the terminal. Runtimes MUST ignore consoleSize if terminal is false or unset.
    • height (uint, REQUIRED)
    • width (uint, REQUIRED)
  • cwd (string, REQUIRED) is the working directory that will be set for the executable. This value MUST be an absolute path.
  • env (array of strings, OPTIONAL) with the same semantics as IEEE Std 1003.1-2008's environ.
  • args (array of strings, OPTIONAL) with similar semantics to IEEE Std 1003.1-2008 execvp's argv. This specification extends the IEEE standard in that at least one entry is REQUIRED (non-Windows), and that entry is used with the same semantics as execvp's file. This field is OPTIONAL on Windows, and commandLine is REQUIRED if this field is omitted.
  • commandLine (string, OPTIONAL) specifies the full command line to be executed on Windows. This is the preferred means of supplying the command line on Windows. If omitted, the runtime will fall back to escaping and concatenating fields from args before making the system call into Windows.

POSIX process

For systems that support POSIX rlimits (for example Linux and Solaris), the process object supports the following process-specific properties:

Linux Process

For Linux-based systems, the process object supports the following process-specific properties.

  • apparmorProfile (string, OPTIONAL) specifies the name of the AppArmor profile for the process. For more information about AppArmor, see AppArmor documentation.

  • capabilities (object, OPTIONAL) is an object containing arrays that specifies the sets of capabilities for the process. Valid values are defined in the capabilities(7) man page, such as CAP_CHOWN. Any value which cannot be mapped to a relevant kernel interface MUST cause an error. capabilities contains the following properties:

    • effective (array of strings, OPTIONAL) the effective field is an array of effective capabilities that are kept for the process.
    • bounding (array of strings, OPTIONAL) the bounding field is an array of bounding capabilities that are kept for the process.
    • inheritable (array of strings, OPTIONAL) the inheritable field is an array of inheritable capabilities that are kept for the process.
    • permitted (array of strings, OPTIONAL) the permitted field is an array of permitted capabilities that are kept for the process.
    • ambient (array of strings, OPTIONAL) the ambient field is an array of ambient capabilities that are kept for the process.
  • noNewPrivileges (bool, OPTIONAL) setting noNewPrivileges to true prevents the process from gaining additional privileges. As an example, the no_new_privs article in the kernel documentation has information on how this is achieved using a prctl system call on Linux.

  • oomScoreAdj (int, OPTIONAL) adjusts the oom-killer score in [pid]/oom_score_adj for the process's [pid] in a proc pseudo-filesystem. If oomScoreAdj is set, the runtime MUST set oom_score_adj to the given value. If oomScoreAdj is not set, the runtime MUST NOT change the value of oom_score_adj.

    This is a per-process setting, where as disableOOMKiller is scoped for a memory cgroup. For more information on how these two settings work together, see the memory cgroup documentation section 10. OOM Contol.

  • selinuxLabel (string, OPTIONAL) specifies the SELinux label for the process. For more information about SELinux, see SELinux documentation.

User

The user for the process is a platform-specific structure that allows specific control over which user the process runs as.

POSIX-platform User

For POSIX platforms the user structure has the following fields:

Note: symbolic name for uid and gid, such as uname and gname respectively, are left to upper levels to derive (i.e. /etc/passwd parsing, NSS, etc)

Example (Linux)

"process": {
    "terminal": true,
    "consoleSize": {
        "height": 25,
        "width": 80
    },

            "CAP_KILL",
            "CAP_NET_BIND_SERVICE"
        ],
       "permitted": [
            "CAP_AUDIT_WRITE",
            "CAP_KILL",
            "CAP_NET_BIND_SERVICE"
        ],
       "inheritable": [
            "CAP_AUDIT_WRITE",
            "CAP_KILL",
            "CAP_NET_BIND_SERVICE"
        ],
        "effective": [
            "CAP_AUDIT_WRITE",
            "CAP_KILL"
        ],
        "ambient": [

        ]
    },
    "rlimits": [
        {
            "type": "RLIMIT_NOFILE",
            "hard": 1024,
            "soft": 1024
        }
    ]
}

Example (Solaris)

"process": {
    "terminal": true,
    "consoleSize": {
        "height": 25,
        "width": 80
    },
    "user": {

        "umask": 7,
        "additionalGids": [2, 8]
    },
    "env": [
        "PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin",
        "TERM=xterm"
    ],
    "cwd": "/root",
    "args": [
        "/usr/bin/bash"
    ]
}

Windows User

For Windows based systems the user structure has the following fields:

  • username (string, OPTIONAL) specifies the user name for the process.

Example (Windows)

"process": {
    "terminal": true,
    "user": {
        "username": "containeradministrator"
    },
    "env": [
        "VARIABLE=1"
    ],
    "cwd": "c:\\foo",
    "args": [
        "someapp.exe",
    ]
}

Hostname

Example

"hostname": "mrsdalloway"

Platform-specific configuration

Example (Linux)

{
    "linux": {
        "namespaces": [
            {
                "type": "pid"
            }
        ]
    }
}

POSIX-platform Hooks

For POSIX platforms, the configuration structure supports hooks for configuring custom actions related to the lifecycle of the container.

  • hooks (object, OPTIONAL) MAY contain any of the following properties:
    • prestart (array of objects, OPTIONAL, DEPRECATED) is an array of prestart hooks.
    • createRuntime (array of objects, OPTIONAL) is an array of createRuntime hooks.
      • Entries in the array contain the following properties (the entries are identical to the entries in the deprecated prestart hooks):
      • The value of path MUST resolve in the runtime namespace.
      • The createRuntime hooks MUST be executed in the runtime namespace.
    • createContainer (array of objects, OPTIONAL) is an array of createContainer hooks.
      • Entries in the array have the same schema as createRuntime entries.
      • The value of path MUST resolve in the runtime namespace.
      • The createContainer hooks MUST be executed in the container namespace.
    • startContainer (array of objects, OPTIONAL) is an array of startContainer hooks.
      • Entries in the array have the same schema as createRuntime entries.
      • The value of path MUST resolve in the container namespace.
      • The startContainer hooks MUST be executed in the container namespace.
    • poststart (array of objects, OPTIONAL) is an array of poststart hooks.
      • Entries in the array have the same schema as createRuntime entries.
      • The value of path MUST resolve in the runtime namespace.
      • The poststart hooks MUST be executed in the runtime namespace.
    • poststop (array of objects, OPTIONAL) is an array of poststop hooks.
      • Entries in the array have the same schema as createRuntime entries.
      • The value of path MUST resolve in the runtime namespace.
      • The poststop hooks MUST be executed in the runtime namespace.

Hooks allow users to specify programs to run before or after various lifecycle events. Hooks MUST be called in the listed order. The state of the container MUST be passed to hooks over stdin so that they may do work appropriate to the current state of the container.

Prestart

The prestart hooks MUST be called after the start operation is called but before the user-specified program command is executed. On Linux, for example, they are called after the container namespaces are created, so they provide an opportunity to customize the container (e.g. the network namespace could be specified in this hook).

Note: prestart hooks were deprecated in favor of createRuntime, createContainer and startContainer hooks, which allow more granular hook control during the create and start phase.

The prestart hooks' path MUST resolve in the runtime namespace. The prestart hooks MUST be executed in the runtime namespace.

CreateRuntime Hooks

The createRuntime hooks MUST be called as part of the create operation after the runtime environment has been created (according to the configuration in config.json) but before the pivot_root or any equivalent operation has been executed.

The createRuntime hooks' path MUST resolve in the runtime namespace. The createRuntime hooks MUST be executed in the runtime namespace.

On Linux, for example, they are called after the container namespaces are created, so they provide an opportunity to customize the container (e.g. the network namespace could be specified in this hook).

The definition of createRuntime hooks is currently underspecified and hooks authors, should only expect from the runtime that the mount namespace have been created and the mount operations performed. Other operations such as cgroups and SELinux/AppArmor labels might not have been performed by the runtime.

Note: runc originally implemented prestart hooks contrary to the spec, namely as part of the create operation (instead of during the start operation). This incorrect implementation actually corresponds to createRuntime hooks. For runtimes that implement the deprecated prestart hooks as createRuntime hooks, createRuntime hooks MUST be called after the prestart hooks.

CreateContainer Hooks

The createContainer hooks MUST be called as part of the create operation after the runtime environment has been created (according to the configuration in config.json) but before the pivot_root or any equivalent operation has been executed. The createContainer hooks MUST be called after the createRuntime hooks.

The createContainer hooks' path MUST resolve in the runtime namespace. The createContainer hooks MUST be executed in the container namespace.

For example, on Linux this would happen before the pivot_root operation is executed but after the mount namespace was created and setup.

The definition of createContainer hooks is currently underspecified and hooks authors, should only expect from the runtime that the mount namespace and different mounts will be setup. Other operations such as cgroups and SELinux/AppArmor labels might not have been performed by the runtime.

StartContainer Hooks

The startContainer hooks MUST be called before the user-specified process is executed as part of the start operation. This hook can be used to execute some operations in the container, for example running the ldconfig binary on linux before the container process is spawned.

The startContainer hooks' path MUST resolve in the container namespace. The startContainer hooks MUST be executed in the container namespace.

Poststart

The poststart hooks MUST be called after the user-specified process is executed but before the start operation returns. For example, this hook can notify the user that the container process is spawned.

The poststart hooks' path MUST resolve in the runtime namespace. The poststart hooks MUST be executed in the runtime namespace.

Poststop

The poststop hooks MUST be called after the container is deleted but before the delete operation returns. Cleanup or debugging functions are examples of such a hook.

The poststop hooks' path MUST resolve in the runtime namespace. The poststop hooks MUST be executed in the runtime namespace.

Summary

See the below table for a summary of hooks and when they are called:

Name Namespace When
prestart (Deprecated) runtime After the start operation is called but before the user-specified program command is executed.
createRuntime runtime During the create operation, after the runtime environment has been created and before the pivot root or any equivalent operation.
createContainer container During the create operation, after the runtime environment has been created and before the pivot root or any equivalent operation.
startContainer container After the start operation is called but before the user-specified program command is executed.
poststart runtime After the user-specified process is executed but before the start operation returns.
poststop runtime After the container is deleted but before the delete operation returns.

            "args": ["cleanup.sh", "-f"]
        }
    ]
}

Annotations

annotations (object, OPTIONAL) contains arbitrary metadata for the container. This information MAY be structured or unstructured. Annotations MUST be a key-value map. If there are no annotations then this property MAY either be absent or an empty map.

Keys MUST be strings. Keys MUST NOT be an empty string. Keys SHOULD be named using a reverse domain notation - e.g. com.example.myKey. Keys using the org.opencontainers namespace are reserved and MUST NOT be used by subsequent specifications. Runtimes MUST handle unknown annotation keys like any other unknown property.

Values MUST be strings. Values MAY be an empty string.

"annotations": {
    "com.example.gpu-cores": "2"
}

Extensibility

Runtimes MAY log unknown properties but MUST otherwise ignore them. That includes not generating errors if they encounter an unknown property.

Valid values

Runtimes MUST generate an error when invalid or unsupported values are encountered. Unless support for a valid value is explicitly required, runtimes MAY choose which subset of the valid values it will support.
