我正在尝试在Docker容器中设置Couchbase和sync_gateway，但是当sync_gateway尝试连接数据库时，出现了一些奇怪的auth错误。
Couchbase在其容器上运行正常，当我将sync_gateway设置为使用GUEST用户时，它能够连接到couchbase。 问题是，我真的想用我创build的用户名/密码，然后我设置了couchbase容器。
我知道couchbase正在工作，因为我可以从localhost:8091上的web界面访问它，并使用我创build的用户名/密码login。 但是sync_gateway引发了我在试图从configuration文件中访问用户名/密码时发出的错误。
Dockerfile
FROM couchbase/server ENTRYPOINT ["/code/scripts/entrypoint.sh", "couchbase-server"]
这是entrypoint.sh
#!/bin/bash cb_cli() { ${CB_CLI} ${@} ${CREDENTIALS} } server_configured() { server_list=$(cb_cli server-list) return $([[ $? == 0 ]] && [[ $(echo ${server_list} | wc -l) != 0 ]]) } setup_couchbase_server() { cb_cli cluster-init --cluster-ramsize=${RAM_SIZE} --cluster-username=admin --cluster-password=admin123 cb_cli bucket-create --bucket-ramsize=${RAM_SIZE} --bucket=${BUCKET_NAME} } couchbase_config() { curl ${SERVER_ADDR} >&- 2>&- while [[ $? != 23 ]]; do sleep 3 curl ${SERVER_ADDR}>&- 2>&- done ! server_configured && { echo "Setting up couchbase server..." setup_couchbase_server && echo "Setup complete" } } [[ "$1" == "couchbase-server" ]] && { /usr/sbin/runsvdir-start & couchbase_config echo "Starting Couchbase Server -- Web UI available at http://${SERVER_ADDR} and logs available in /opt/couchbase/var/lib/couchbase/logs" /usr/sbin/runsvdir-start }
泊坞窗，compose.yml

最后，这是我运行docker-compose时遇到的错误：

这是棘手的，但事实certificate，在configuration文件中的用户名和密码引用的是存储桶而不是couchbase服务器。 答案是在创build存储桶时包含密码。 文件entrypoint.sh setup_couchbase_server如下所示：
setup_couchbase_server() { cb_cli cluster-init --cluster-ramsize=${CB_RAM_SIZE} cb_cli bucket-create --bucket-ramsize=${CB_RAM_SIZE} --bucket=${CB_SYNC_GATEWAY_BUCKET} --bucket-password=bucket_pass }
那么用户名必须与存储桶名称相同。 现在起作用了。
