通过Dockerfile从部署到App Engine的Ghost连接到Google Cloud SQL
我正在按照本教程将Ghost部署到Google App Engine
但是,不建议将Ghost安装为NPM模块的方法。
本教程介绍了一种通过Dockerfile安装Ghost的方法。 /ghost-appengine/
我正在尝试通过使用此Dockerfile将Ghost部署到Google App Engine,并连接到我的Google Cloud SQL数据库。
但是我遇到了问题:
ERROR: (gcloud.app.deploy) Error Response: [9]
Application startup error:
[2019-10-03 21:10:46] ERROR connect ENOENT /cloudsql/ghost
connect ENOENT /cloudsql/ghost
"Unknown database error"
Error ID:
500
Error Code:
ENOENT
----------------------------------------
DatabaseError: connect ENOENT /cloudsql/ghost
at DatabaseError.KnexMigrateError (/var/lib/ghost/versions/2.31.1/node_modules/knex-migrator/lib/errors.js:7:26)
在第一个教程中,它提到了在启动ghost之前需要运行迁移,以防止出现此问题。因此,我尝试在Dockerfile中添加此行
RUN npm install knex-migrator --no-save
RUN NODE_ENV=production node_modules/knex-migrator init --mgpath node_modules/ghost
但是随后出现以下错误:
/bin/sh: 1: node_modules/knex-migrator: Permission denied
The command '/bin/sh -c NODE_ENV=production node_modules/knex-migrator init --mgpath node_modules/ghost' returned a non-zero code: 126
如何在运行Ghost之前将我的Dockerfile配置为迁移数据库,以确保它可以连接到Cloud SQL数据库?

回答如下:根据Connecting from App Engine页面,您需要将路径更新为/cloudsql/INSTANCE_CONNECTION_NAME
(因此是/cloudsql/redacted:us-central1:ghost
)。
