# <a name="solarisApplicationContainerConfiguration" />Solaris Application Container Configuration
|
||
|
|
|
||
|
|
Solaris application containers can be configured using the following properties, all of the below properties have mappings to properties specified under [zonecfg(1M)][zonecfg.1m_2] man page, except milestone.
|
||
|
|
|
||
|
|
## <a name="configSolarisMilestone" />milestone
|
||
|
|
The SMF(Service Management Facility) FMRI which should go to "online" state before we start the desired process within the container.
|
||
|
|
|
||
|
|
**`milestone`** *(string, OPTIONAL)*
|
||
|
|
|
||
|
|
### Example
|
||
|
|
```json
|
||
|
|
"milestone": "svc:/milestone/container:default"
|
||
|
|
```
|
||
|
|
|
||
|
|
## <a name="configSolarisLimitpriv" />limitpriv
|
||
|
|
The maximum set of privileges any process in this container can obtain.
|
||
|
|
The property should consist of a comma-separated privilege set specification as described in [priv_str_to_set(3C)][priv-str-to-set.3c] man page for the respective release of Solaris.
|
||
|
|
|
||
|
|
**`limitpriv`** *(string, OPTIONAL)*
|
||
|
|
|
||
|
|
### Example
|
||
|
|
```json
|
||
|
|
"limitpriv": "default"
|
||
|
|
```
|
||
|
|
|
||
|
|
## <a name="configSolarisMaxShmMemory" />maxShmMemory
|
||
|
|
The maximum amount of shared memory allowed for this application container.
|
||
|
|
A scale (K, M, G, T) can be applied to the value for each of these numbers (for example, 1M is one megabyte).
|
||
|
|
Mapped to `max-shm-memory` in [zonecfg(1M)][zonecfg.1m_2] man page.
|
||
|
|
|
||
|
|
**`maxShmMemory`** *(string, OPTIONAL)*
|
||
|
|
|
||
|
|
### Example
|
||
|
|
```json
|
||
|
|
"maxShmMemory": "512m"
|
||
|
|
```
|
||
|
|
|
||
|
|
## <a name="configSolarisCappedCpu" />cappedCPU
|
||
|
|
Sets a limit on the amount of CPU time that can be used by a container.
|
||
|
|
The unit used translates to the percentage of a single CPU that can be used by all user threads in a container, expressed as a fraction (for example, .75) or a mixed number (whole number and fraction, for example, 1.25).
|
||
|
|
An ncpu value of 1 means 100% of a CPU, a value of 1.25 means 125%, .75 mean 75%, and so forth.
|
||
|
|
When projects within a capped container have their own caps, the minimum value takes precedence.
|
||
|
|
cappedCPU is mapped to `capped-cpu` in [zonecfg(1M)][zonecfg.1m_2] man page.
|
||
|
|
|
||
|
|
* **`ncpus`** *(string, OPTIONAL)*
|
||
|
|
|
||
|
|
### Example
|
||
|
|
```json
|
||
|
|
"cappedCPU": {
|
||
|
|
"ncpus": "8"
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## <a name="configSolarisCappedMemory" />cappedMemory
|
||
|
|
The physical and swap caps on the memory that can be used by this application container.
|
||
|
|
A scale (K, M, G, T) can be applied to the value for each of these numbers (for example, 1M is one megabyte).
|
||
|
|
cappedMemory is mapped to `capped-memory` in [zonecfg(1M)][zonecfg.1m_2] man page.
|
||
|
|
|
||
|
|
* **`physical`** *(string, OPTIONAL)*
|
||
|
|
* **`swap`** *(string, OPTIONAL)*
|
||
|
|
|
||
|
|
### Example
|
||
|
|
```json
|
||
|
|
"cappedMemory": {
|
||
|
|
"physical": "512m",
|
||
|
|
"swap": "512m"
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## <a name="configSolarisNetwork" />Network
|
||
|
|
|
||
|
|
### <a name="configSolarisAutomaticNetwork" />Automatic Network (anet)
|
||
|
|
anet is specified as an array that is used to set up networking for Solaris application containers.
|
||
|
|
The anet resource represents the automatic creation of a network resource for an application container.
|
||
|
|
The zones administration daemon, zoneadmd, is the primary process for managing the container's virtual platform.
|
||
|
|
One of the daemon's responsibilities is creation and teardown of the networks for the container.
|
||
|
|
For more information on the daemon see the [zoneadmd(1M)][zoneadmd.1m] man page.
|
||
|
|
When such a container is started, a temporary VNIC(Virtual NIC) is automatically created for the container.
|
||
|
|
The VNIC is deleted when the container is torn down.
|
||
|
|
The following properties can be used to set up automatic networks.
|
||
|
|
For additional information on properties, check the [zonecfg(1M)][zonecfg.1m_2] man page for the respective release of Solaris.
|
||
|
|
|
||
|
|
* **`linkname`** *(string, OPTIONAL)* Specify a name for the automatically created VNIC datalink.
|
||
|
|
* **`lowerLink`** *(string, OPTIONAL)* Specify the link over which the VNIC will be created.
|
||
|
|
Mapped to `lower-link` in the [zonecfg(1M)][zonecfg.1m_2] man page.
|
||
|
|
* **`allowedAddress`** *(string, OPTIONAL)* The set of IP addresses that the container can use might be constrained by specifying the `allowedAddress` property.
|
||
|
|
If `allowedAddress` has not been specified, then they can use any IP address on the associated physical interface for the network resource.
|
||
|
|
Otherwise, when `allowedAddress` is specified, the container cannot use IP addresses that are not in the `allowedAddress` list for the physical address.
|
||
|
|
Mapped to `allowed-address` in the [zonecfg(1M)][zonecfg.1m_2] man page.
|
||
|
|
* **`configureAllowedAddress`** *(string, OPTIONAL)* If `configureAllowedAddress` is set to true, the addresses specified by `allowedAddress` are automatically configured on the interface each time the container starts.
|
||
|
|
When it is set to false, the `allowedAddress` will not be configured on container start.
|
||
|
|
Mapped to `configure-allowed-address` in the [zonecfg(1M)][zonecfg.1m_2] man page.
|
||
|
|
* **`defrouter`** *(string, OPTIONAL)* The value for the OPTIONAL default router.
|
||
|
|
* **`macAddress`** *(string, OPTIONAL)* Set the VNIC's MAC addresses based on the specified value or keyword.
|
||
|
|
If not a keyword, it is interpreted as a unicast MAC address.
|
||
|
|
For a list of the supported keywords please refer to the [zonecfg(1M)][zonecfg.1m_2] man page of the respective Solaris release.
|
||
|
|
Mapped to `mac-address` in the [zonecfg(1M)][zonecfg.1m_2] man page.
|
||
|
|
* **`linkProtection`** *(string, OPTIONAL)* Enables one or more types of link protection using comma-separated values.
|
||
|
|
See the protection property in dladm(8) for supported values in respective release of Solaris.
|
||
|
|
Mapped to `link-protection` in the [zonecfg(1M)][zonecfg.1m_2] man page.
|
