hyper container as client

Instructions for data migration

  • Install and config the command line tool in your running hyper container

  • Upload volume data from the hyper container to your own server or cloud storage with cli

Prerequisites

Any of the following

  • You have your own file server

    • SFTP server with public IP

    • SSH server with public IP

  • You have your own cloud storage

    • AWS S3

    • Google Cloud Storage

    • Azure Blob Storage

    • ...

Example

SFTP/SSH Server

You should have the IP, Port, username, and password of your own SFTP/SSH server.

Example: copy file from the hyper container to the SFTP server

$ hyper exec -it mycontainer sh
root@5cd5b9fe7b2a:~# which sftp
/usr/bin/sftp
root@5cd5b9fe7b2a:~# tar czvf /data/hello.tar.gz /data/hello.txt
root@5cd5b9fe7b2a:~# sftp -P 2222 /data/hello.tar.gz foo@209.177.93.134:/data

Example: copy file from hyper container to the SSH server

$ hyper exec -it mycontainer sh
root@5cd5b9fe7b2a:~# which scp
/usr/bin/scp
root@5cd5b9fe7b2a:~# tar czvf /data/hello.tar.gz /data/hello.txt
root@5cd5b9fe7b2a:~# scp -P 2222 /data/hello.tar.gz foo@209.177.93.134:/data

If your server has keypairs, you can create the private key file in the hyper container.

$ hyper exec -it mycontainer sh
root@5cd5b9fe7b2a:~# which scp
/usr/bin/scp
root@5cd5b9fe7b2a:~#  cat > key.pem <<EOF
<content of the private key>
EOF
root@5cd5b9fe7b2a:~#  chmod 400 key.pem
root@5cd5b9fe7b2a:~# scp -i key.pem -P 2222 /data/hello.tar.gz foo@209.177.93.134:/data
root@5cd5b9fe7b2a:~# rm -rf key.pem

AWS S3

REF:

Step:

  • create a temporary credential with AWS console first, then you will get AWS Access Key and AWS Secret Access Key

  • install and config aws cli in the hyper container

  • compress files in the volume

  • copy compressed file to s3

$ hyper exec -it mycontainer sh
root@5cd5b9fe7b2a:~# apt-get update
root@5cd5b9fe7b2a:~# apt-get install -y python-dev python-pip
root@5cd5b9fe7b2a:~# pip install awscli

root@5cd5b9fe7b2a:~# aws --profile temp configure
AWS Access Key ID [None]: xxx
AWS Secret Access Key [None]: xxx
Default region name [None]:
Default output format [None]:

root@5cd5b9fe7b2a:~# aws --profile temp s3 mb s3://hyper-backup-bucket

root@5cd5b9fe7b2a:~# aws --profile temp s3 cp /data/hello.txt s3://hyper-backup-bucket/data/hello.txt

root@5cd5b9fe7b2a:~# aws --profile temp s3 sync /data/ s3://hyper-backup-bucket/data/

Google Cloud Storage

REF:

Run the following command lines in the hyper container

// install gsutil
root@a52aa7ba39b4:/# curl https://sdk.cloud.google.com | bash


// init gcloud
root@a52aa7ba39b4:/# source /root/.bashrc
root@a52aa7ba39b4:/# gcloud init
...
Go to the following link in your browser:

    https://accounts.google.com/o/oauth2/auth?redirect_uri=urn%3Aietf%3Awg%3Aoauth%3A2.0%3Aoob&prompt=select_account&response_type=code&client_id=32555940559.apps.googleusercontent.com&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fuserinfo.email+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcloud-platform+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fappengine.admin+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcompute+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Faccounts.reauth&access_type=offline

...


// create bucket
root@a52aa7ba39b4:/# gsutil mb -l us-east1 gs://hyper-backup-bucket/
Creating gs://hyper-backup-bucket/...

// copy file from hyper container to google cloud storage
root@a52aa7ba39b4:/# cd /home/backupdata/data/
root@a52aa7ba39b4:/home/backupdata/data# gsutil cp data.tar.gz gs://hyper-backup-bucket/
Copying file://data.tar.gz [Content-Type=application/x-tar]...

Azure Blob Storage

REF:

There is no example here, but it is similar to the example above.
