Pourquoi est-docker construire corrompre le JSON $VSS_NUGET_EXTERNAL_FEED_ENDPOINTS?
Je suis à l'aide de cet article (plus précisément l'exemple 2 qui utilise Buildkit et docker construire des secrets) pour l'aider à remplir ma Dockerfile. Le processus:
- passer un PAT lors de
docker build, - monter le PAT comme un secret,
- exportation d'un échappé de la chaîne JSON à l'aide de la secret (via
cat /pat) à l'ENV, et- ^^^ ci-dessus JSON est corrompu ^^^
- l'utilisation de la variable env pour appeler un NuGet privé d'alimentation avant
- faire un
dotnet restoredemande.
La commande bash en question est:
RUN --mount=type=secret,id=pat,dst=/pat export VSS_NUGET_EXTERNAL_FEED_ENDPOINTS="{\"endpointCredentials\": [{\"endpoint\":\"https://<my private feed URL>/nuget/v3/index.json\", \"username\":\"docker\", \"password\":\"`cat /pat`\"}]}" && \
echo $VSS_NUGET_EXTERNAL_FEED_ENDPOINTS
La sortie de la commande echo (notez le point à la fin de la PAT est ajouté APRÈS le JSON fermeture des accolades):
{"endpointCredentials": [{"endpoint":"https://<my private feed URL>/nuget/v3/index.json", "username":"docker", "password":"qwak...jiq5"}]}vtzkzv4a
Lorsque je lance la commande de bash (dans le sous-système Windows pour Linux), il fonctionne parfaitement:
~ echo "my-pat-token" >> /pat
~ export MY_ENV_VAR="{\"endpointCredentials\": [{\"endpoint\":\"https://<URL of private feed>/nuget/v3/index.json\", \"username\":\"build\", \"password\":\"`cat /pat`\"}]}"
~ echo $MY_ENV_VAR
{"endpointCredentials": [{"endpoint":"https://<URL of private feed>/nuget/v3/index.json", "username":"build", "password":"my-pat-token"}]}
