Passo 1: configure o projeto e o repositório de origem

Neste passo, configura o Google Cloud projeto e o ambiente Python no Cloud Shell, ativa as APIs necessárias e atribui as funções de gestão de identidade e de acesso (IAM) de que precisa para concluir o tutorial. Também configura um repositório do GitHub que contém os ficheiros de origem da app ao criar um fork e clonar o repositório GoogleCloudPlatform/generative-ai. Depois de concluir estes passos, valide a configuração executando e testando a app localmente no Cloud Shell.

Antes de começar

Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.
In the Google Cloud console, on the project selector page, select or create a Google Cloud project.
Roles required to select or create a project
• Select a project: Selecting a project doesn't require a specific IAM role—you can select any project that you've been granted a role on.
• Create a project: To create a project, you need the Project Creator (roles/resourcemanager.projectCreator), which contains the resourcemanager.projects.create permission. Learn how to grant roles.
Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.
Go to project selector
Verify that billing is enabled for your Google Cloud project.
Enable the Vertex AI, Compute Engine, Artifact Registry, Identity-Aware Proxy (IAP), Cloud Run Admin, Cloud Build, Identity and Access Management (IAM) API, and Gemini for Google Cloud APIs.
Roles required to enable APIs
To enable APIs, you need the Service Usage Admin IAM role (roles/serviceusage.serviceUsageAdmin), which contains the serviceusage.services.enable permission. Learn how to grant roles.
Enable the APIs
Make sure that you have the following role or roles on the project: Vertex AI User, Cloud Build Editor, Cloud Run Admin, Artifact Registry Admin, Compute Load Balancer Admin, Service Account User, IAP Policy Admin, OAuth Config Editor, and Service Usage Admin.
Check for the roles
1. In the Google Cloud console, go to the IAM page.

   Go to IAM
2. Select the project.

3. In the Principal column, find all rows that identify you or a group that you're included in. To learn which groups you're included in, contact your administrator.

4. For all rows that specify or include you, check the Role column to see whether the list of roles includes the required roles.
Grant the roles
1. In the Google Cloud console, go to the IAM page.

   Aceder ao IAM
2. Selecione o projeto.
3. Clique em Conceder acesso.

4. No campo Novos responsáveis, introduza o identificador do utilizador. Normalmente, este é o endereço de email de uma Conta Google.

5. Na lista Selecionar uma função, selecione uma função.
6. Para conceder funções adicionais, clique em Adicionar outra função e adicione cada função adicional.
7. Clique em Guardar.

In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

Configure o repositório de origem

1. No GitHub, crie um fork do repositório GoogleCloudPlatform/generative-ai. Saiba mais sobre a criação de forks de repositórios no GitHub.

   Crie uma bifurcação do repositório no GitHub

2. In the Google Cloud console, activate Cloud Shell.

   Activate Cloud Shell

   At the bottom of the Google Cloud console, a Cloud Shell session starts and displays a command-line prompt. Cloud Shell is a shell environment with the Google Cloud CLI already installed and with values already set for your current project. It can take a few seconds for the session to initialize.

3. No terminal do Cloud Shell, execute os seguintes comandos para clonar o repositório bifurcado e definir o diretório gemini-streamlit-cloudrun
   como o diretório ativo:

   cd
   git clone https://github.com/GIT_USER_NAME/FORK_NAME/
   cd FORK_NAME/gemini/sample-apps/gemini-streamlit-cloudrun

   Substitua o seguinte:

   • GIT_USER_NAME: o seu nome de utilizador do GitHub.
   • FORK_NAME: o nome do repositório de fork que acabou de criar no GitHub.

Configure o ambiente e as dependências

1. No terminal do Cloud Shell, execute os seguintes comandos para configurar um ambiente virtual:

   python3 -m venv gemini-streamlit
   source gemini-streamlit/bin/activate
   pip install -r requirements.txt
   

2. Execute os seguintes comandos para definir as variáveis de ambiente necessárias para a inicialização do Vertex AI:

   export GCP_PROJECT=$GOOGLE_CLOUD_PROJECT
   export GCP_REGION='us-central1' 
   

Teste a app localmente

1. No terminal do Cloud Shell, execute a app com o seguinte comando:

   streamlit run app.py \
     --browser.serverAddress=localhost \
     --server.enableCORS=false \
     --server.enableXsrfProtection=false \
     --server.port 8080
   

2. Para pré-visualizar a app, na barra de tarefas do Cloud Shell, clique em e, de seguida, em Pré-visualizar na porta 8080.
