Um código bem simples apenas para printar um hello world.</p> <p><a href="https://res.cloudinary.com/practicaldev/image/fetch/s--vd7D_nau--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/co3aygqacevmqsln5ikc.png" class="article-body-image-wrapper"><img src="https://res.cloudinary.com/practicaldev/image/fetch/s--vd7D_nau--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/co3aygqacevmqsln5ikc.png" alt="main.go" width="468" height="464"></a></p> <p>Depois de criado o código da Lambda, é necessário rodar o comando para criar o módulo Go.</p> <p><a href="https://res.cloudinary.com/practicaldev/image/fetch/s--CvZEufp2--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/kh88tlsoc8iflebtdze4.png" class="article-body-image-wrapper"><img src="https://res.cloudinary.com/practicaldev/image/fetch/s--CvZEufp2--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/kh88tlsoc8iflebtdze4.png" alt="go mod init" width="523" height="106"></a></p> <p>Os arquivos go.mod e go.sum foram criados.<br> Depois de criada a Lambda, vamos partir para o Terraform.<br> Vamos utilizar ele para provisionar a infra do projeto.</p> <p><a href="https://res.cloudinary.com/practicaldev/image/fetch/s--gZ_anpUr--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/6y6afp1jwmh961zr14yw.png" class="article-body-image-wrapper"><img src="https://res.cloudinary.com/practicaldev/image/fetch/s--gZ_anpUr--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/6y6afp1jwmh961zr14yw.png" alt="main.tf" width="800" height="861"></a></p> <p>Repare que utilizamos o runtime provided.al2023, que é o runtime mais novo criado pela AWS e também o architecture arm64.</p> <p>Depois do arquivo de terraform criado, vamos criar o Github Actions para funcionar como nosso CI/CD.<br> Crie um arquivo chamado pipeline.yml dentro da pasta .github/workflows.</p> <p>Como vamos usar uma Lambda em ARM64, temos algumas peculiaridades no momento de fazer o build. Temos que passar as variáveis GOOS=linux GOARCH=arm64.</p> <p><a href="https://res.cloudinary.com/practicaldev/image/fetch/s--RKcpI7Fu--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/6tixk9liux2fdvmj1hg1.png" class="article-body-image-wrapper"><img src="https://res.cloudinary.com/practicaldev/image/fetch/s--RKcpI7Fu--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/6tixk9liux2fdvmj1hg1.png" alt="Github Actions" width="627" height="514"></a></p> <p>Agora no job de deploy vamos fazer o terraform init, format check, validate, plan e apply, para validar se tudo está correto e realmente provisionar a infra.</p> <p><a href="https://res.cloudinary.com/practicaldev/image/fetch/s--h9dWQe6N--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/27prabta8b5kp342bb5x.png" class="article-body-image-wrapper"><img src="https://res.cloudinary.com/practicaldev/image/fetch/s--h9dWQe6N--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/27prabta8b5kp342bb5x.png" alt="Github Actions" width="688" height="1058"></a></p> <p>Outro ponto importante, para conseguirmos fazer todo o provisionamento na AWS precisamos passar para o Terraform algumas chaves de acesso. Como não é nada recomendado deixar as chaves no arquivo do Actions, Eu acabei deixando elas no secret do Github.</p> <p><a href="https://res.cloudinary.com/practicaldev/image/fetch/s--W33V8qSr--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/2wkmo7lcfod8x6zq1g1p.png" class="article-body-image-wrapper"><img src="https://res.cloudinary.com/practicaldev/image/fetch/s--W33V8qSr--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/2wkmo7lcfod8x6zq1g1p.png" alt="Github Actions" width="547" height="181"></a></p> <p>Depois do push com as alterações a pipeline vai ficar assim:</p> <p><a href="https://res.cloudinary.com/practicaldev/image/fetch/s--KbL3fwd0--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/uu2vxnopq91q9qkib636.png" class="article-body-image-wrapper"><img src="https://res.cloudinary.com/practicaldev/image/fetch/s--KbL3fwd0--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/uu2vxnopq91q9qkib636.png" alt="Github Actions" width="800" height="383"></a></p> <p><a href="https://res.cloudinary.com/practicaldev/image/fetch/s--a7uhNEqb--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/umj6d1h07eblz7rsa0q7.png" class="article-body-image-wrapper"><img src="https://res.cloudinary.com/practicaldev/image/fetch/s--a7uhNEqb--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/umj6d1h07eblz7rsa0q7.png" alt="Github Actions" width="729" height="462"></a></p> <p><a href="https://res.cloudinary.com/practicaldev/image/fetch/s--EIo3JkAe--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/6akgt4a6qt4pjjjvqalz.png" class="article-body-image-wrapper"><img src="https://res.cloudinary.com/practicaldev/image/fetch/s--EIo3JkAe--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/6akgt4a6qt4pjjjvqalz.png" alt="Github Actions" width="737" height="588"></a></p> <p>Caso tudo funcione perfeitamente(eu sei, eu sei... nada funciona de primeira rsrs) a Lambda será criada na AWS.</p> <p><a href="https://res.cloudinary.com/practicaldev/image/fetch/s--U-ppOiju--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/i5p3j9e6ost6gh1zzlon.png" class="article-body-image-wrapper"><img src="https://res.cloudinary.com/practicaldev/image/fetch/s--U-ppOiju--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_800/https://dev-to-uploads.s3.amazonaws.com/uploads/articles/i5p3j9e6ost6gh1zzlon.png" alt="AWS Lambda" width="800" height="837"></a></p> <p>E... voilà, Lambda funcionando!</p> <p>Todo o código está nesse repo: <a href="https://github.com/FRSiqueiraBR/go-terraform-lambda">https://github.com/FRSiqueiraBR/go-terraform-lambda</a></p> <p>Criei essa Lambda pra usar de base para outros projetos pessoais, esperam que tenham gostado, deixem sugestões e melhorias nos comentários ✋.
