Here you can modify the port on which the frontend application will be served :
{code}
server:
applicationConnectors:
- type: http
port: 8080
bindHost: 56.158.30.50
{code}
*bindHost* will set your default connector host IP. If not overridden in _artifactServer_ section, it will also be used by the artifact server. It is optional and will be localhost (127.0.0.1) by default.
h3. Artifact server
This section configures the artifact server, which is responsible of serving artifacts (from cockpit backend to Petals containers) while deployed using cockpit interface.
{code}
artifactServer:
temporaryPath: /tmp/petals-cockpit-artifacts
externalHost: 56.158.30.10
{code}
*temporaryPath:* Local file location while artifact is served. (Default "\{java.io.tmpdir\}/petals-cockpit-artifacts")
*externalHost:* This host overrides _bindHost_ in the address sent to petals to download artifacts. Thus default is _server.applicationConnectors.bindHost_.
h3. Database
This section allows you to choose which database the backend will use.
You can specify the adress, driver and user/password to connect to the database.
{code}
database:
driverClass: org.h2.Driver
user: petals
password: petals
url: jdbc:h2:./db/cockpit
validationQuery: "/* Health Check */ SELECT 1"
{code}
{warning}Petals Cockpit *0.22.0* has only been tested with H2 database. Be careful changing this.
Validation query may have to be adapted as well to the chosen DB.{warning}
h3. Logging
This section allows you to choose where and how logs are displayed and archived. Dropwizard provides a rather customisable configuration system, this is the default for Petals Cockpit:
{code}
server:
requestLog:
appenders:
- type: file
currentLogFilename: ./logs/cockpit-access.log
archivedLogFilenamePattern: ./logs/cockpit-access-%d.log.gz
logging:
#Global logging setting
level: INFO
#Specific cockpit loggers settings
#(will bypass the console threshold & filter)
loggers:
"org.ow2.petals.cockpit.server":
level: INFO
appenders:
- type: console
#File logging uses global setting, console filters out global cockpit output
#(to avoid duplicates from previous specific logger)
appenders:
- type: file
currentLogFilename: ./logs/cockpit.log
archivedLogFilenamePattern: ./logs/cockpit-%d.log.gz
archivedFileCount: 5
- type: console
threshold: WARN
filterFactories:
- type: cockpit-server-filter-factory
{code}
*server.requestLog.appenders* allows to choose where to log all REST requests reaching the server.
*logging.appenders* allows to choose where to log the application output, you can filter it by logging level. Levels can be *OFF, ERROR, WARN, INFO, DEBUG, TRACE, or ALL.*
* *logging.level* is the global level for the application output, it controls directly what will be found in *logging.appenders.type: file* (_./logs/cockpit.log_)
* *logging.appenders.threshold* (under type: console) is the level that will be displayed in the console from all sources (except from _org.ow2.petals.cockpit.server.\*_). Cannot be set lower than global level.
* *logging.loggers* allows to set specific loggers at independent levels. Here you can set any specific java class or package to the desired level on top of the rest.
This way, by default, output from _org.ow2.petals.cockpit.server.\*_ java classes (petals cockpit code specifically) will be displayed under INFO level. While global output (from dropwizard framework or other dependencies) will remain at WARN level in the console.
The console filter _cockpit-server-filter-factory_ filters out all output from _org.ow2.petals.cockpit.server.*,_ in order to prevent duplicates from the specific logger it is advised to leave it.
h3. Using LDAP
{warning}
LDAP connection is fully available since Petals Cockpit *0.27.0*. Previous builds may not have this feature operational.
{warning}
If an LDAP configuration section is added to the configuration file, Cockpit will go in LDAP mode. When in this mode, users (even admin) will only be able to log in Cockpit if they credentials are validated by the configured LDAP. If configuration is wrong or LDAP is down, user will not be able to log in. To use LDAP, add these lines :
{code}
ldapConfig:
url: ldap://10.31.4.167:389
usersDn: ou=personnes,dc=my-domain,dc=com
usernameAttribute: uid
nameAttribute: cn
passwordAttribute: password
principalDn: uid=admin,ou=personnes,dc=my-domain,dc=com
principalPassword: adminpass
{code}
|| Parameter || Optionnal || Default || Description ||
| url | no | \- | URL to reach LDAP instance |
| usersDn | no | \- | Distinguished name |
| usernameAttribute | yes | uid | Attribute name used on LDAP to uniquely identify a user |
| nameAttribute | yes | cn | Attribute name used on LDAP as user display name |
| passwordAttribute | yes | password | Attribute name used on LDAP as password |
| principalDn | no | \- | Dn of the technical LDAP account |
| principalPassword | no | \- | Password of the technical LDAP account |
The technical LDAP account is used to request the LDAP server, thus it must have read rights on LDAP server.
Petals cockpit is not designed to be able to switch LDAP authentication on and off with a same installation. Users added through LDAP are not available without it, and vice versa. If you want to activate or deactivate LDAP authentication, it is advised to wipe the database in the meantime.
h2. Launching Petals Cockpit
When you launch Petals Cockpit for the first time, a Database will be created (if none was found at configured URL).
Also, if no user were found in the database, a token will be be generated in order to add an administrator using the web interface. For instance :
{quote}
WARN \[2018-04-24 12:19:58,370\] org.ow2.petals.cockpit.server.CockpitApplication: No users are present in the database: setup your installation via [http://127.0.1.1:8080/setup?token=t3Zm5A8MtNUcRJgHPxwc]
{quote}
Be sure to have logging correctly set up for it to display.
There are also parameters and commands usable at launch.
h3. Using parameters
Parameters can be added to the launching script *petals-cockpit.sh* :
|| Name || Description ||
| *\--no-db-migrate* | At startup, db version is automatically migrated to the version embedded in the jar file. *This options allows you to skip this migration (not recommended).* |
| *\--no-db-check* | if *\--no-db-migrate* is set, the status of the database will be checked. If it is not up to date, the application will exit. *This option allows you to skip this check (not recommended).* |
| *\--debug* | This option will launch Petals Cockpit in debug mode. Allowing an IDE (for instance: Eclipse) to *connect to it via port 5000* and benefit from debugging functionalities such as breakpoints and variable inspection. |
Example:
{code}
$ ./petals-cockpit.sh --debug --no-db-migrate
{code}
h3. Using commands
h4. Adding user and workspace
The *add-user* command allows you to add a user
|| Argument || Short argument || Optionnal || Default || Description ||
| \--username | \-u | no | \- | The user's id, also his login. |
| \--name | \-n | no | \- | The name under which the user will appear. |
| \--password | \-p | yes/no | \- | The user's password. Required only for non-LDAP users. |
| \--admin | \-a | yes | \- | Whether the user will be added as an admin or not. |
| \--ldapUser | \-l | yes | \- | Whether the user to add is an LDAP user or not. |
| \--workspacename | \-w | yes | \- | The user's workspace. Which will be created and set as current workspace for the user. |
Example:
Adding a non admin user without workspace
{code}
$ ./petals-cockpit.sh add-user -u myUserName -n myName -p myPassword
{code}
Adding an admin user with workspace
{code}
$ ./petals-cockpit.sh add-user --username myUserName --name myName -p myPassword -w myWorkspace -a
{code}
Adding an LDAP admin user
{code}
$ ./petals-cockpit.sh add-user --username myUserName --name myName -l -a
{code}
h1. Managing users
h2. Logging in
When connecting to the web application, you have to log in. Type in your *username* and *password* to do so.
<img login>
h3. Adding the first admin with token
If no admin are present in the database, you can add one on the setup page. You will have to fill the *token* field with the token provided by the backend (if you used the link *\{ip\}:\{port\}/setup?token=\{token\}* the token field will be pre-filled).
*In normal mode* (not LDAP), you must fill the *username*, *password* and *name* fields to be able to add the user.
*In LDAP mode*, only the *username* field is present and you must fill it with a valid LDAP username.
Once all the fields are filled, click the button to add your first admin.
After adding the user, you will be redirected to the login page by clicking the button.
<img login token>
h2. Administrating users
If you are an Administrator, you have access to the Administration page. To go there click on the gear icon on the top right corner. <img administration gear icon>
<img user administration page>
h3. Adding a new user
By clicking on "ADD A NEW USER" you can open a form to add a new user.
*In normal mode* (not LDAP), you must fill the *username*, *password* and *name* fields to be able to add the user.
*In LDAP mode*, only the *username* field is present and you must fill it with a valid LDAP username.
Then click the button to add the user.
h3. Managing existing users
You can see the list of existing users.
By clicking on a user an edition form will unfold.
*In normal mode* (not LDAP), you can modify users to change their *name* and / or *password* (username cannot be changed) or *delete* them. Type new values in the corresponding field to change them. Leaving password empty will not change their password. Then click "SAVE".
*In LDAP mode*, you can only *delete* users.
h2. Using user preferences
Once logged, you can access user preferences by clicking on the profile icon in the top right corner (the one on the far right).
<img user pref logo>
h3. Changing theme
Here you can select the GUI theme. For now, this preference is stored locally on you browser local storage and is linked to the server address (Meaning each cockpit backend instance will have a shared theme set for any users using the same browser on the same machine).
h1. Managing workspace
h2. The workspace perspective
The _workspace perspective_ is the perspective that opens by default when launching *Petals Cockpit*.
The *workspace* is the entity that preserve the project and their contents. We can represent this as a directory.
It aims to manage the different elements that make up the workspace: in particular the import of one or more *[Petals buses|https://doc.petalslink.com/pages/viewpage.action?pageId=1803735]* and the configuration of the elements related to it as well as consultation of existing services.
The access to a workspace is limited to its users (see [Managing workspace users)|#Managing workspace users|Managing workspace users])
By default, this perspective contains the following windows :
* The _Workspaces_ view displays the workspaces accessible by the authenticated user and allows to add new ones by clicking on the button (view list button) in the top left corner near the workspace name;
* The _Workspace_ view that allows you to obtain information about a workspace (description and list of users) is accessible by clicking on the button with its name in the top left corner or in the selection window at workspace;
* The _Bus Import_ view displays a specific import form with controls on the input fields. To access it, just click the button \(+) in the side panel next to the search bar;
* The _Petals_ view which allows to obtain a tree with all the elements attached to the bus. These elements are also called *resources*. Each of these resources has a detailed view (overview), some also have an operations view;
* The _Services_ view provides a detailed view of the service names and their dependencies.
h3. Creating the first workspace
Once logged in, you must set a name to your workspace. Then click on the button (new folder button) to add it.
You can then set the workspace description and manage the authorized users.
h3. Adding a new workspace
You can create as many workspaces as you want, but by default they will all be empty.
It will be necessary to select the one you wish to work on by simply clicking on it.
<img workspaces list>
h2. Selecting workspace
Once workspace loaded, you will be redirected to the workspace page.
<img workspace overview>
h3. Adding a description
By clicking on the edit icon from the whiteboard description area, you can put a specific description using markup formatting: **markdown*\*.
Then click “SUBMIT” to save or “CANCEL” if you want reset description.
h3. Managing workspace users
By clicking on the input field from the users area, a list of users name will unfold. You can then:
* Add a user on this workspace by selecting a user and clicking "ADD";
* Delete them by clicking delete button.
h3. Removing workspace
It is only possible to delete a workspace when in its view. Just click on the delete button at the top right of the page and confirm the deletion by clicking "DELETE".
Be sure you want to do this because everything in this workspace will no longer exist for you but also for other users.
You will then be redirected to the list of available workspaces.
h3. Navigating between workspaces
It is possible to browse the list of available workspaces for the user (ie, having access to it) and navigate between the workspaces. You have to open the workspaces list view, and click the workspace of your choice to load it.
h1. Working with buses
Buses are a representation of a [Petals topology|https://doc.petalslink.com/display/petalsesb510/Topology+Configuration], composed of registries, domains and containers. For now, only containers are represented in Petals Cockpit.
In Cockpit, _importing a bus_ means connecting to one of its containers (providing containers credentials and topology passphrase) in order to get topology informations from it. Then it tries to establish connection to all containers declared in the topology, gathering their informations in cockpit DB. Once _imported_, the bus and its containers are displayed in the Petals tab tree view.
<img petals tree view>
h2. Managing buses
h3. Importing a bus
In the Petals tab view, click on the add \(+) icon located in the top right corner of the tab panel, right next to the search bar. The _Workspace Bus Import_ view will open:
<img workspace bus import>
There you can fill all mandatory informations to connect to a Topology:
* *IP* (or *hostname)* and *port*: of a container to connect to it.
* *Username* and *password*: credentials to connect to the container.
* *Topology passphrase*: to allow accessing topology data.
At all time, fields can be cleared by clicking the *CLEAR* button.
Once all fields are filled, the *IMPORT* button will activate, click on it to start importing the Bus. This will create an _IMPORT IN PROGRESS_ item.
h3. Managing import in progress
As topology can be quite complex and distributed among several distant locations, importing a whole topology can take some time. Thus, while this action is performed on the server of cockpit, _IMPORT IN PROGRESS_ view (accessed by clicking on an item) will allow you to keep track and take actions. Once imported, the bus in progress should automatically disappear from the _IMPORTS IN PROGRESS_ and the imported bus show in the _BUSES_ section.
Should a bus import fail, it will remain as failed bus in progress until deleted. You can click on it to see the error that prevented the import.
Both imports in progress and failed imports can be discarded using the *CANCEL* (or *DISCARD*) button. You can also click on *DISCARD AND RETRY* to discard the import and reopen the import form (keeping ip, port and username fields pre-filled). Password and Passphrase are not kept and must always be provided again.
h3. Deleting a bus
To delete a bus, click on the Bus item, then click on the delete icon (red icon with a garbage bin). A popup will ask you again if you wan to delete the bus, or cancel the action. Note: Buses are only deleted from the worskpace, they are not shown anymore in cockpit but the bus itself is not impacted. If the bus was also imported in another workspace before being deleted, it will remain imported in the other workspace.
h2. Visiting bus overview
By clicking on a bus item, you can go to its overview page. It will show the bus description and its containers. You can click on a container to go to the associated container overview.
h1. Working with containers
When a container is selected in Petals tree, containers views are displayed in the right frame. Two tabs are available: container *OVERVIEW* and *OPERATIONS*, they are explained in the container view section.
There are also optional subsections under each container (*COMPONENTS*, *SERVICE ASSEMBLIES* and *SHARED LIBRARIES*) that will appear in the Petals tree if one of the corresponding artifact is deployed on the container.
h2. Container views
h3. Container overview
This view displays:
* An *{_}About{_}* card that shows the IP and Port used to connect to the container (via JMX RMI)
* A *{_}System info{_}* card that displays information returned by the container
* A *{_}Container reachabilities{_}* card that displays a graph of this container topology and the reachabilities of containers. Clicking on a container node will select it in the graph; displaying IP and Port of selected container, and a button _View this container_ jumping to the selected container overview.
h3. Container operations
Cockpit can be used as artifact server to deploy artifacts on a container. The files will first be uploaded to cockpit backend, which will in turn serve them (via an http server) to the container in order to deploy them.
{note}
If you are experiencing issues connecting a container and the backend see the [Artifact server|#Artifact server|Artifact server] section.
