Docker Secrets #32

RussellNS · 2019-08-04T23:51:00Z

There is no support for 'Docker Secrets' in this image. The setup for Docker Secrets may be different between Docker Swarm and Docker Compose. However, the end result is the same. A plain text file will end up inside the container at '/run/secrets/' where each file will contain 1 secret (account name, password, etc.). The contents of this plain text file is then available to the entrypoint of the container.

The current build of this container uses these example environment variables:

    MYSQL_ROOT_PASSWORD: hguyFtgfR4r9R4r76
    MYSQL_DATABASE: wordpressdb
    MYSQL_USER: wordpressuser
    MYSQL_PASSWORD: hguyFt6S95dgfR4ryb
    MYSQL_CHARSET: utf8mb4
    MYSQL_COLLATION: utf8mb4_general_ci

The code that handles the environment variables appears to be in 'run.sh':

    if [ "$MYSQL_ROOT_PASSWORD" = "" ]; then
        MYSQL_ROOT_PASSWORD=`pwgen 16 1`
        echo "[i] MySQL root Password: $MYSQL_ROOT_PASSWORD"
    fi

    MYSQL_DATABASE=${MYSQL_DATABASE:-""}
    MYSQL_USER=${MYSQL_USER:-""}
    MYSQL_PASSWORD=${MYSQL_PASSWORD:-""}

The normal construct for using Docker Secrets is to use the same environment variable name(s), but with '_FILE' appended, thereby allowing the use of both the original environment variable or the path that contains the 'secret' value. The filename used for the secret is made up entirely by the user, but is usually something meaningful. Example:

    MYSQL_ROOT_PASSWORD_FILE: /run/secrets/db_root_pass
    MYSQL_DATABASE_FILE: /run/secrets/db_name
    MYSQL_USER_FILE: /run/secrets/db_admin_name
    MYSQL_PASSWORD_FILE: /run/secrets/db_admin_pass
    MYSQL_CHARSET: /run/secrets/db_charset
    MYSQL_COLLATION: /run/secrets/db_collation

Would it be possible to change this code to use docker secrets (i.e. parse the specified file in /run/secrets) for the information for these variables?

Proposed Example 'docker-compose.yml':

  services:
    mariadb:
      image: yobasystems/alpine-mariadb
      environment:
        MYSQL_ROOT_PASSWORD_FILE: /run/secrets/db_root_pass
        MYSQL_DATABASE_FILE: /run/secrets/db_name
        MYSQL_USER_FILE: /run/secrets/db_admin_name
        MYSQL_PASSWORD_FILE: /run/secrets/db_admin_pass
        MYSQL_CHARSET_FILE: /run/secrets/db_charset
        MYSQL_COLLATION_FILE: /run/secrets/db_collation

      secrets:
        - db_root_pass
        - db_name
        - db_admin_name
        - db_admin_pass
        - db_charset
        - db_collation
      expose:
        - "3306"
      volumes:
        - /data/example/mysql:/var/lib/mysql
      restart: always

  secrets:
    db_root_pass:
      file: ./private/db_root_pass.txt
    db_name:
      file: ./private/db_name.txt
    db_admin_name:
      file: ./private/db_admin_name.txt
    db_admin_pass:
      file: ./private/db_admin_pass.txt
    db_charset:
      file: ./private/db_charset.txt
    db_collation:
      file: ./private/db_collation.txt

Proposed Example 'run.sh' Code Change:

if [ "$MYSQL_ROOT_PASSWORD_FILE" = "" ]; then
    if [ "$MYSQL_ROOT_PASSWORD" = "" ]; then
        MYSQL_ROOT_PASSWORD=`pwgen 16 1`
        echo "[i] MySQL root Password: $MYSQL_ROOT_PASSWORD"
    fi
else
    MYSQL_ROOT_PASSWORD=`cat $MYSQL_ROOT_PASSWORD_FILE`
    echo "[i] MySQL Root Password: $MYSQL_ROOT_PASSWORD"
fi

if [ "$MYSQL_DATABASE_FILE" = "" ]; then
    MYSQL_DATABASE=${MYSQL_DATABASE:-""}
else
    MYSQL_DATABASE=`cat $MYSQL_DATABASE_FILE`
    echo "[i] MySQL Database Name: $MYSQL_DATABASE"
fi

if [ "$MYSQL_USER_FILE" = "" ]; then
    MYSQL_USER=${MYSQL_USER:-""}
else
    MYSQL_USER=`cat $MYSQL_USER_FILE`
    echo "[i] MySQL User Name: $MYSQL_USER"
fi

if [ "$MYSQL_PASSWORD_FILE" = "" ]; then
    MYSQL_PASSWORD=${MYSQL_PASSWORD:-""}
else
    MYSQL_PASSWORD=`cat $MYSQL_PASSWORD_FILE`
    echo "[i] MySQL User Password: $MYSQL_PASSWORD"
fi

if [ "$MYSQL_CHARSET_FILE" = "" ]; then
    MYSQL_CHARSET=${MYSQL_CHARSET:-""}
else
    MYSQL_CHARSET=`cat $MYSQL_CHARSET_FILE`
    echo "[i] MySQL User Password: $MYSQL_CHARSET"
fi

if [ "$MYSQL_COLLATION_FILE" = "" ]; then
    MYSQL_COLLATION=${MYSQL_COLLATION:-""}
else
    MYSQL_COLLATION=`cat $MYSQL_COLLATION_FILE`
    echo "[i] MySQL User Password: $MYSQL_COLLATION"
fi

Assuming that each 'db_*.txt' file referenced above contained the original example values, then this would allow users to provide both of these with the same result:

    MYSQL_ROOT_PASSWORD: hguyFtgfR4r9R4r76
    MYSQL_DATABASE: wordpressdb
    MYSQL_USER: wordpressuser
    MYSQL_PASSWORD: hguyFt6S95dgfR4ryb
    MYSQL_CHARSET: utf8mb4
    MYSQL_COLLATION: utf8mb4_general_ci

and

    MYSQL_ROOT_PASSWORD_FILE: /run/secrets/db_root_pass
    MYSQL_DATABASE_FILE: /run/secrets/db_name
    MYSQL_USER_FILE: /run/secrets/db_admin_name
    MYSQL_PASSWORD_FILE: /run/secrets/db_admin_pass
    MYSQL_CHARSET_FILE: /run/secrets/db_charset
    MYSQL_COLLATION_FILE: /run/secrets/db_collation

Also, in the event that a user provides both secret and non-secret values for the same thing (i.e. MYSQL_USER and MYSQL_USER_FILE), the secret value will override the non-secret value in this proposed code change.

Thank you for your attention.

Up! This would be awesome for Docker Swarm clusters.

dominictayloruk · 2020-01-17T16:45:30Z

I'll have a look at this, i don't use swarm so will have to setup a test environment.

There is more info available here & here.

Seems it's only relevant to swarm;

About secrets
In terms of Docker Swarm services, a secret is a blob of data, such as a password, SSH private key, SSL certificate, or another piece of data that should not be transmitted over a network or stored unencrypted in a Dockerfile or in your application’s source code. In Docker 1.13 and higher, you can use Docker secrets to centrally manage this data and securely transmit it to only those containers that need access to it. Secrets are encrypted during transit and at rest in a Docker swarm. A given secret is only accessible to those services which have been granted explicit access to it, and only while those service tasks are running.

am-mnandor · 2020-04-01T14:40:01Z

Also relevant to k8s, I guess.

dominictayloruk · 2020-07-16T15:06:16Z

If this is relevant to k8s then it should be next on my list. I can test that i just don't use swarm.

medilies · 2020-10-30T12:30:22Z

Was this solved?
Because I did a secret test right now with mariadb service.
I opened bash inside a mariadb container
Did #cat /run/secrets/mysecret the value is correctly there
Did # printenv it showed
MYSQL_ROOT_PASSWORD_FILE=/run/secrets/mysecret
But connecting to the DB tells me access denied

@dominictayloruk
if you add 01_secret-init.sh (below) to /scripts/pre-init.d, it should automatically detect environmental variables named var_name__FILE (where the key is double-underscore-FILE). Due to the nature of posix sh, we have to use an 'eval' hack for indirect variable reference. If you install bash and update run.sh and 01_secret-init.sh to use bash, we can replace eval SECRETFILE="\$${VARNAME}" with `SECRETFILE=${!VARNAME}, etc.

#!/bin/sh

for FULLVAR in $(env | grep "^.*__FILE="); do
    # trim "=..." from variable name

    echo "[secret-init] Evaluating ${VARNAME}"

    # set SECRETFILE to the contents of the variable

    if [[ -f ${SECRETFILE} ]]; then
        # strip the appended "__FILE" from environmental variable name
        STRIPVAR=$(echo $VARNAME | sed "s/__FILE//g")
        # echo "[secret-init] Set STRIPVAR to ${STRIPVAR}"  # DEBUG - rm for prod!

        # set value to contents of secretfile

        # echo "[secret_init] Set ${STRIPVAR} to $(eval echo \$${STRIPVAR})"  # DEBUG - rm for prod!
        
        export "${STRIPVAR}"
        echo "[secret-init] Success! ${STRIPVAR} set from ${VARNAME}"
        
    else
        echo "[secret-init] ERROR: Cannot find secret in ${VARNAME}"
    fi
done

I've just tested the latest version 10.5.8 and run a fresh container with secrets injected and they have created the database with the values i entered to the secret.

The bit needed for Kubernetes in the yaml:

    spec:
      containers:
      - envFrom:
        - secretRef:
            name: this-is-the-secret-name

It should also work in swarm and most other orchestration systems.

BTW I'm using this on both Ubuntu & Alpine hosts running k3s 1.20.6 on amd64/armhf/arm64

Looking to close this issue as secrets can be used in Kubernetes.

Ideally if anyone can test in swarm that would be good.

dominictayloruk · 2021-06-02T09:35:09Z

Fixed, issue now closed.

Jarige · 2022-08-28T17:09:40Z

This got closed but I have two remarks:

The readme file does not mention the possibility of using secrets at all.
It does not seem to work for me using Portainer in Swarm mode. And when I look at the source it does not seem to include the script that's mentioned above either. Neither do I see any reference in run.sh to FILE and the /scripts/pre-init.d/ directory is empty.
So I'm kinda doubtful as to whether this got fixed at all.

dominictayloruk · 2022-08-30T09:57:10Z

Yeah this got closed as the secrets are getting injected although i haven't confirmed on swarm as i don't use swarm but happy to reopen for testing if it's not working for you. In relation to your questions;

1, Yeah the readme doesn't contain any info on secrets, maybe i can add some more info with further testing to confirm.
2,The script folder is empty as it's there for you to include custom scripts, like the one above or any other script to be run before/after the container has initiated. You would bind mount a file into the directory like;

-v /data/mariadb/01_secret-init.sh:/scripts/pre-init.d/01_secret-init.sh

I'll have to spin up a swarm cluster to test as i only use Kubernetes. I'll also re-open the issue as it requires more testing.

dominictayloruk · 2022-08-30T11:12:06Z

Just done a quick check to test the secrets in swarm by creating some secrets and checking they are accessible inside the container

printf "hguyFtgfR4r9R4r76" | docker secret create MYSQL_ROOT_PASSWORD -
printf "wordpressdb" | docker secret create MYSQL_DATABASE -
printf "wordpressuser" | docker secret create MYSQL_USER -
printf "hguyFt6S95dgfR4ryb" | docker secret create MYSQL_PASSWORD -
printf "utf8mb4" | docker secret create MYSQL_CHARSET -
printf "utf8mb4_general_ci" | docker secret create MYSQL_COLLATION -

Check the secrets on the manager

docker secret ls

Now lets create the service

docker service create \
     --name mariadb \
     --secret MYSQL_ROOT_PASSWORD \
     --secret MYSQL_DATABASE \
     --secret MYSQL_USER \
     --secret MYSQL_PASSWORD \
     --secret MYSQL_CHARSET \
     --secret MYSQL_COLLATION \

Secrets not used in container initialisation!!!

Tested another way but still no secrets in the container;

docker service create \
     --name mariadb2 \
     --replicas 1 \
     --secret source=MYSQL_ROOT_PASSWORD,target=mysql_root_password \
     --secret source=MYSQL_PASSWORD,target=mysql_password \
     --secret source=MYSQL_USER,target=mysql_user \
     --secret source=MYSQL_DATABASE,target=mysql_database \
     -e MYSQL_ROOT_PASSWORD_FILE="/run/secrets/mysql_root_password" \
     -e MYSQL_PASSWORD_FILE="/run/secrets/mysql_password" \
     -e MYSQL_USER_FILE="/run/secrets/mysql_user" \
     -e MYSQL_DATABASE_FILE="/run/secrets/mysql_database" \
