# Targets
|
|
|
|
A target is a resource
|
|
that represents a networked service
|
|
with an associated set of permissions
|
|
a [user][] can connect to
|
|
and interact with
|
|
through Boundary
|
|
by way of a session.
|
|
A target can only be defined within a [project][].
|
|
A target can contain references to [host sets][] from [host catalogs][]
|
|
which belong to the same project as the target.
|
|
A target can contain references to [credential libraries][]
|
|
from [credential stores][] which belong to the same project as the target.
|
|
A target can contain an address
|
|
which is used by a session to connect to a networked resource.
|
|
A target cannot have an address and also reference host sources.
|
|
A user must be assigned a [role][] with the `authorize-session` [permission][]
|
|
for the target to
|
|
establish a session with a networked resource by way of an address,
|
|
or host in any host set referenced by the target.
|
|
|
|
## Attributes
|
|
|
|
A target has the following configurable attributes:
|
|
|
|
- `name` - (required)
|
|
The `name` must be unique within the target's [project][].
|
|
|
|
- `description` - (optional)
|
|
|
|
- `address` - (optional)
|
|
Represents a network resource address and is used when establishing a session.
|
|
Accepts no port, only an IP address or DNS name.
|
|
|
|
### TCP Target Attributes
|
|
|
|
TCP targets have the following additional attributes:
|
|
|
|
- `address` - (optional)
|
|
A valid network address for the target to connect to.
|
|
This value cannot be used alongside host sources.
|
|
|
|
- `default_port` - (optional)
|
|
The default port to set on this target.
|
|
|
|
- `egress_worker_filter` - (optional)
|
|
A boolean expression to [filter][] which egress workers can handle sessions
|
|
for this target.
|
|
|
|
- `ingress_worker_filter` - (optional) <sup>HCP Only</sup>
|
|
A boolean expression to [filter][] which ingress workers can handle sessions
|
|
for this target.
|
|
|
|
- `session_connection_limit` - (required)
|
|
The cumulative number of TCP connections allowed during a session.
|
|
A -1 value means no limit.
|
|
The default is -1.
|
|
The value must be greater than 0 or exactly -1.
|
|
|
|
- `session_max_seconds` - (required)
|
|
The maximum duration of an individual session between the user and the target.
|
|
All connections for a session are closed
|
|
and the session is terminated
|
|
when a session reaches the maximum duration.
|
|
The default is 8 hours (28800 seconds).
|
|
This value must be greater than 0.
|
|
|
|
### SSH Target Attributes <sup>HCP Only</sup>
|
|
|
|
SSH targets can source username/password or SSH private key credentials from Vault [credential libraries][] or static
|
|
[credentials][]. Boundary then injects credentials into the SSH session between a client and end host. This allows users to
|
|
securely connect to remote hosts using SSH, while never being in possession of a valid credential for that target host.
|
|
|
|
SSH targets have the following additional attributes:
|
|
|
|
- `address` - (optional)
|
|
A valid network address for the target to connect to.
|
|
This value cannot be used alongside host sources.
|
|
|
|
- `default_port` - (optional)
|
|
The default port to set on this target.
|
|
|
|
- `egress_worker_filter` - (optional)
|
|
A boolean expression to [filter][] which egress workers can handle sessions
|
|
for this target.
|
|
|
|
- `ingress_worker_filter` - (optional) <sup>HCP Only</sup>
|
|
A boolean expression to [filter][] which ingress workers can handle sessions
|
|
for this target.
|
|
|
|
- `session_connection_limit` - (required)
|
|
The cumulative number of TCP connections allowed during a session.
|
|
A -1 value means no limit.
|
|
The default is -1.
|
|
The value must be greater than 0 or exactly -1.
|
|
|
|
- `session_max_seconds` - (required)
|
|
The maximum duration of an individual session between the user and the target.
|
|
All connections for a session are closed
|
|
and the session is terminated
|
|
when a session reaches the maximum duration.
|
|
The default is 8 hours (28800 seconds).
|
|
This value must be greater than 0.
