# `ui` Block
|
|
|
|
<Placement groups={['ui']} />
|
|
|
|
The `ui` block configures the Nomad agent's [web UI].
|
|
|
|
```hcl
|
|
ui {
|
|
enabled = true
|
|
|
|
content_security_policy {
|
|
connect_src = ["*"]
|
|
default_src = ["'none'"]
|
|
form_action = ["'none'"]
|
|
frame_ancestors = ["'none'"]
|
|
img_src = ["'self'","data:"]
|
|
script_src = ["'self'"]
|
|
style_src = ["'self'","'unsafe-inline'"]
|
|
}
|
|
|
|
consul {
|
|
ui_url = "https://consul.example.com:8501/ui"
|
|
}
|
|
|
|
vault {
|
|
ui_url = "https://vault.example.com:8200/ui"
|
|
}
|
|
|
|
label {
|
|
text = "Staging Cluster"
|
|
background_color = "yellow"
|
|
text_color = "#000000"
|
|
}
|
|
}
|
|
```
|
|
|
|
A default `ui` block is automatically merged with all Nomad agent
|
|
configurations. Note that the UI can be served from any Nomad agent,
|
|
and the configuration is individual to each agent.
|
|
## `ui` Parameters
|
|
- `enabled` `(bool: true)` - Specifies whether the web UI is
|
|
enabled. If disabled, the `/ui/` path will return an empty web page.
|
|
|
|
- `consul` <code>([Consul]: nil)</code> - Configures integrations
|
|
between the Nomad web UI and the Consul web UI.
|
|
|
|
- `vault` <code>([Vault]: nil)</code> - Configures integrations
|
|
between the Nomad web UI and the Vault web UI.
|
|
|
|
- `label` <code>([Label]: nil)</code> - Configures a user-defined
|
|
label to display in the Nomad Web UI header.
|
|
|
|
## `content_security_policy` Parameters
|
|
|
|
The `content_security_policy` block configures the HTTP
|
|
[Content-Security-Policy](https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP)
|
|
header sent with the web UI response.
|
|
|
|
- `connect_src` `(array<string>: ["*"])` - Specifies the valid sources for
|
|
`connect-src` in the Content Security Policy header.
|
|
- `default_src` `(array<string>: ["'none'"])` - Specifies the valid sources for
|
|
`default-src` in the Content Security Policy header.
|
|
- `form_action` `(array<string>: ["'none'"])` - Specifies the valid sources for
|
|
`form-action` in the Content Security Policy header.
|
|
- `frame_ancestors` `(array<string>: ["'none'"])` - Specifies the valid sources
|
|
for `frame-ancestors` in the Content Security Policy header.
|
|
- `img_src` `(array<string>: ["'self'", "data:"])` - Specifies the valid sources
|
|
for `img-src` in the Content Security Policy header.
|
|
- `script_src` `(array<string>: ["'self'"])` - Specifies the valid sources for
|
|
`script-src` in the Content Security Policy header.
|
|
- `style_src` `(array<string>: ["'self'","'unsafe-inline'"])` - Specifies the
|
|
valid sources for `style-src` in the Content Security Policy header.
|
|
|
|
## `consul` Parameters
|
|
|
|
- `ui_url` `(string: "")` - Specifies the full base URL to a Consul
|
|
web UI (for example: `https://consul.example.com:8501/ui`. This URL
|
|
is used to build links from the Nomad web UI to a Consul web
|
|
UI. Note that this URL will not typically be the same one used for
|
|
the agent's [`consul.address`]; the `consul.address` is the URL used
|
|
by the Nomad to communicate with Consul, whereas the
|
|
`ui.consul.ui_url` is the URL you'll visit in your browser. If
|
|
this field is omitted, this integration will be disabled.
|
|
|
|
## `vault` Parameters
|
|
|
|
- `ui_url` `(string: "")` - Specifies the full base URL to a Vault
|
|
web UI (for example: `https://vault.example.com:8200/ui`. This URL
|
|
is used to build links from the Nomad web UI to a Vault web
|
|
UI. Note that this URL will not typically be the same one used for
|
|
the agent's [`vault.address`]; the `vault.address` is the URL used
|
|
by the Nomad to communicate with Vault, whereas the
|
|
`ui.vault.ui_url` is the URL you'll visit in your browser. If
|
|
this field is omitted, this integration will be disabled.
|
|
|
|
## `label` Parameters
|
|
|
|
- `text` `(string: "")` - Specifies the text of the label that will be
|
|
displayed in the header of the Web UI.
|
|
- `background_color` `(string: "")` - The background color of the label to
|
|
be displayed. The Web UI will default to a black background. HEX values
|
|
may be used.
|
|
- `text_color` `(string: "")` - The text color of the label to be displayed.
|
|
The Web UI will default to white text. HEX values may be used.
