Kubernetes pull image from Gitlab

Boa tarde,

Estou tentando pegar a no yaml de configuração do yaml usando o codigo abaixo:

apiVersion: apps/v1 kind: Deployment metadata: name: backend-deployment labels: app: backend-deployment spec: selector: matchLabels: app: backend-pod template: metadata: labels: app: backend-pod spec: containers: - image: registry.gitlab.com// name: container-backend-apistructure ports: - containerPort: 8086 imagePullSecrets: - name: gitlab-auth

Configurei a secret com o comando abaixo: kubectl create secret docker-registry gitlab-auth --docker-server=registry.gitlab.com --docker-username= --docker-password= --docker-email=

mas no console do kubernetes eh exibido a mensagem abaixo:

Olá Marco,

Acabou não saindo a mensagem de erro, poderia por favor colocar ela aqui para darmos uma olhada?

Obrigado

Olá Marco,

Pelo que vi está aparecendo erro ImagePullBackOff, isso normalmente ocorre quando a imagem não está mais disponível ou você não configurou a permissão de acesso para essa imagem.

Sua configuração imagePullPolicy está como Always, com isso o Kubernetes sempre irá tentar fazer o acesso a essa imagem, mas como ele não consegue fazer esse acesso, ocorre o erro ImagePullBackOff.

Como sugestão, tente verificar se esta imagem está disponível e se você possui as permissões.

Att

Rafael a imagem esta disponivel e aabaixo, como foi configurado as permissão de acesso permissão com a url documentação para atribuir as permissões:

kubectl create secret docker-registry gitlab-auth --docker-server=registry.gitlab.com --docker-username=maribeiro30 --docker-password= --docker-email=

Essa secret eh referenciada no yaml atraves da chave: imagePullSecrets: - name: gitlab-auth
