docker_remote command for IBM® Db2 Warehouse

Enables you to invoke a Docker command so that it executes on one or more Db2® Warehouse remote nodes.

As a user with host operating system root authority, issue the command as follows:

docker_remote  -n|--node {"remote_node1[,...,remote_nodeN]"|$hosts} -c|--command "docker_command"  [-h|--help]

-n|--node "remote_node1[,...,remote_nodeN]"|"$shell_variable"

Specifies one or more remote nodes. You can specify the nodes in two ways:

By providing a comma-separated list of remote nodes directly after the parameter. Enclose the list in double quotation marks (" ").
By setting a shell variable to a comma-separated list of remote nodes and providing the variable after the parameter. Enclose the variable in double quotation marks.

You can specify the remote nodes as host names or IP addresses.

-c|--command "docker_command"

Specifies a Docker command to execute on the remote node or nodes.

-h|--help

Displays help for the docker_remote command.

Examples

The following command executes the docker ps -a command on the remote node myhost.mydomain.com:
```
docker_remote --node "myhost.mydomain.com" --command "ps -a"
```
The following command executes the docker ps -a command on the remote nodes myhost1.mydomain.com, myhost2.mydomain.com, and myhost3.mydomain.com:
```
docker_remote --node "myhost1.mydomain.com, myhost2.mydomain.com, myhost3.mydomain.com" --command "ps -a"
```
In the following example, the hosts shell variable is set to a comma-separated list of remote nodes and then used as the value of the --node parameter:
```
hosts="myhost1,myhost2,myhost3"
docker_remote --node "$hosts" --command "ps -a"
```
