Dockerfile 中的 Mongorestore

我想创建一个启动 mongo 服务器并自动从以前的版本恢复的 Docker 映像mongodump启动时。

这是我的图像 Dockerfile：

 FROM mongo

 COPY dump /home/dump

 CMD mongorestore /home/dump

当我运行这个时，我遇到了这个错误：

Failed: error connecting to db server: no reachable servers

有什么办法可以得到mongorestore通过 Docker 运行的命令？

在来自的帮助下这个答案 https://stackoverflow.com/a/20354167/3692084，Marc Young 的回答，以及 Dockerfile 参考我能够让这个工作。

Dockerfile

FROM mongo

COPY dump /home/dump
COPY mongo.sh /home/mongo.sh
RUN chmod 777 /home/mongo.sh

CMD /home/mongo.sh

mongo.sh

#!/bin/bash

# Initialize a mongo data folder and logfile
mkdir -p /data/db
touch /var/log/mongodb.log
chmod 777 /var/log/mongodb.log

# Start mongodb with logging
# --logpath    Without this mongod will output all log information to the standard output.
# --logappend  Ensure mongod appends new entries to the end of the logfile. We create it first so that the below tail always finds something
/entrypoint.sh mongod --logpath /var/log/mongodb.log --logappend &

# Wait until mongo logs that it's ready (or timeout after 60s)
COUNTER=0
grep -q 'waiting for connections on port' /var/log/mongodb.log
while [[ $? -ne 0 && $COUNTER -lt 60 ]] ; do
    sleep 2
    let COUNTER+=2
    echo "Waiting for mongo to initialize... ($COUNTER seconds so far)"
    grep -q 'waiting for connections on port' /var/log/mongodb.log
done

# Restore from dump
mongorestore --drop /home/dump

# Keep container running
tail -f /dev/null
