我在docker容器中运行mongodb
,我有数据文件备份。
但今天我删除了mongodb
粗心。
我尝试运行另一个容器并将数据文件放入容器中,但它不起作用。
如何从数据文件中恢复数据?
我使用的容器是tutum / mongodb.my docker-compose.yml文件是
mongo_db:
image: tutum/mongodb
privileged: true
restart: always
ports:
- 27016:27017
- 28016:28017
volumes:
- /var/mongodb:/data/db
environment:
- MONGODB_PASS=xxxxxx
- AUTH=yes
现在我想将我的数据从dirctory / var / mongodb恢复到我的新容器
我把mongod.lock以外的文件放在我的新容器中,但我的mongodb无法运行。 它是截图:
mongod.conf是:
# Where to store the data.
# Note: if you run mongodb as a non-root user (recommended) you may
# need to create and set permissions for this directory manually,
# e.g., if the parent directory isn't mutable by the mongodb user.
dbpath=/var/lib/mongodb
#where to log
logpath=/var/log/mongodb/mongod.log
logappend=true

# Enable the HTTP interface (Defaults to port 28017).
#httpinterface = true
# Turns off server-side scripting. This will result in greatly limited
# functionality
#noscripting = true
# Turns off table scans. Any query that would do a table scan fails.
#notablescan = true
# Disable data file preallocation.

# Specify .ns file size for new databases.
# nssize = <size>

#replSet=setname
# maximum size in megabytes for replication operation log
#oplogSize=1024

容器在容器开始运行时在env中设置STORAGE_ENGINE 容器的环境是:
# mongod.conf
STORAGE_ENGINE=wiredTiger
HOSTNAME=bb544551ec2b
MONGODB_PASS=xxxxxx

这取决于您执行备份的方式。
1 - 你拍了一个文件系统快照 =&GT;您可以在数据文件夹中解压缩快照(查看mongod.conf中数据文件夹的位置)。
2 - 您使用了mongodump命令 =&GT;你需要使用mongorestore命令

我在 mongodb 中挣扎,并且我自己在重新启动时缺乏持久性存储。在这里阅读您的帖子让我想知道这意味着什么:
来自您的 mongod.conf:
以及来自您的环境变量:
也许你的环境应该是:
或
(我也在为这里的降价而苦苦挣扎)
我个人终于能够使用这个 compose 部分来持久化数据——并通过设置一个 ENV 变量 NODE_ENV: production(在依赖于 mongodb 服务的不同服务中)
image: mongo:4.4
restart: always
environment:
MONGO_INITDB_ROOT_USERNAME: something
MONGO_INITDB_ROOT_PASSWORD: otherthanthis
volumes:
