System provides examination testing for students on the basis of the given test tasks.
Student choses a task he wants to complete and reads the terms.
He writes a program according to the task using one of available programming languages.
After sending a solution System executes the code and inputs test datasets. To consider solved correctly, the program must return correct results for all test inputs.
Represents System BackEnd storing all the necessary data.
First, install .Net Core 3.1
-
Create ./WebApp/appsettings.Secret.json file
-
Fill ./WebApp/appsettings.Secret.json with the following:
{
"JwtIssuerOptions": {
"SecretKey":"Random string nearly 30 symbols"
},
"ConnectionStrings": {
"PostgresDataBase": "The connection string to the Postgres database"
},
"EmailSettings": {
"Email": "Email of sender account",
"Password": "Password of sender account",
"SmtpHost": "smtp.host",
"SmtpPort": "smtp.port",
"SmtpUseSsl": true|false
},
"AccountSettings": {
"IsRegisterAvailable": true|false // if false - new users can be added only via control panel
},
"DefaultUserSettings": {
"Email": "email of user, which can be created",
"Password": "password of user, which can be created",
"Name": "name of user, which can be created",
"StudentId": "student id of user, which be created",
"CreateUser": true|false // if true - user with parameters, written above will be created,
"Roles": [ // All roles will be applyed to account with written email, ignoring CreateUser field
"Admin",
"User",
"Executer",
"ResultsViewer"
]
},
"GenerateSettings": {
"Domain": "domain, attached to user email while generating, '@rtuitlab.dev' for example"
},
"RecaptchaSettings": {
"SecretKey": "PRIVATE token got when creating reCAPCTCHA v2"
},
"USE_DEBUG_EMAIL_SENDER": true|false, // if true email messages will be printed to console
"USE_DEBUG_RECAPTCHA_VERIFIER": true|false, // if true recaptcha always will be valid
"USE_CHECKING_RESTART": true|false // if true, solutions the check of which has started more than 2 minutes ago would be placed in the queue again
"USE_MOCK_QUEUE": true|false // if true, mock queue service will be used. If false - rabbitmq queue
}You must use connection string to your real Postgres database in the field ConnectionStrings:PostgresDataBase, for example:
User ID=postgres;Password=password;Server=127.0.0.1;Port=5432;Database=TestDBdotnet;
- Use
dotnet runto start web app in Development environment (appsettings.Development.json will be used)
Application connected to WebApp, which is executing received solutions and checks them.
You must have Docker installed on the system you want to run Executor on. Actually Docker executes received programs.
-
Create ./Executor/appsettings.Local.json
-
Fill it with the following:
{
"StartSettings": {
"Address":"http://localhost:5000", // Address of olympiad webapp
"DockerEndPoint":"http://localhost:2375", // Address of docker endpoint
"PrivateDockerRegistry": { // OPTIONAL, use when you reach rate limit od dockerhub pulls (100 per 6 hours)
"Address": "host of your private registry",
"Login": "login of registry",
"Password": "password of registry"
}
},
"UserInfo": {
"UserName":"Username having Executor rights",
"Password":"User password"
},
"RunningSettings": {
"WorkersPerCheckCount": 5 // Every solution will be checked with that count of parallel workers (valid values - [1..100]), select value according to your machine configuration (for surface book 2 - optimal is 5-10). Too large value can break your docker.
},
"CONSOLE_MODE": "Logs" | "StatusReporting",// Logs - just write logs, StatusReporting - updatable status and 10 last logs with possible artifacts =
"RabbitMqQueueSettings" :{
"Host": "RABBIT MQ HOST",
"QueueName": "QUEUE NAME FOR SOLUTION TASKS",
"ClientProvidedName": "name for executor service"
}
}- After creating the file you can execute
dotnet runin ./Executor folder.
Can be run only with linux docker daemon
