I have this docker-compose.yml file

When I run docker-compose up -d. I can use this command to create a mysql database:

```
docker exec app-name-ci-mysql-container mysql --defaults-extra-file=/my.cnf -e "create database reseraco_ci_testing"

```

where my.cnf is file with my database credentials. And everything works fine. But when I try to move everything to jenkins, it looks weird:

This is my Jenkinsfile

```
pipeline { 
    agent any
    stages {
        stage('Build') { 
            steps { 
                sh 'cd ./ci && docker-compose up -d'
                sh 'sleep 10'
                sh "docker exec app-name-ci-mysql-container mysql --defaults-extra-file=/my.cnf -e \\\"create database reseraco_ci_testing\\\""
            }
        }
        stage('Test'){
            steps {
                sh 'docker exec app-name-ci-php-container /var/www/project/vendor/bin/phpunit'
            }
        }
        stage('Deploy') {
            steps {
                echo "DEPLOYING"
            }
        }
    }
    post {
        always {
            sh 'docker rm app-name-ci-php-container app-name-ci-nginx-container app-name-ci-mysql-container -f'
        }
    }
}

```

And when I try to run the pipeline, I get this:

The Docker Engine you're using is running in swarm mode.

Compose does not use swarm mode to deploy services to multiple nodes in a swarm. All containers will be scheduled on the current node.

To deploy your application across the swarm, use `docker stack deploy`.

  -?, --help          Display this help and exit.
  -I, --help          Synonym for -?
  --auto-rehash       Enable automatic rehashing. One doesn't need to use
                      'rehash' to get table and field completion, but startup
                      and reconnecting may take a longer time. Disable with
                      --disable-auto-rehash.
                      (Defaults to on; use --skip-auto-rehash to disable.)
  -A, --no-auto-rehash 
                      No automatic rehashing. One has to use 'rehash' to get
                      table and field completion. This gives a quicker start of
                      mysql and disables rehashing on reconnect.
  --auto-vertical-output 
                      Automatically switch to vertical output mode if the
                      result is wider than the terminal width.
  -B, --batch         Don't use history file. Disable interactive behavior.
                      (Enables --silent.)
  --bind-address=name IP address to bind to.
  --binary-as-hex     Print binary data as hex

                      Directory for character set files.
  --column-type-info  Display column type information.
  -c, --comments      Preserve comments. Send comments to the server. The
                      default is --skip-comments (discard comments), enable
                      with --comments.
  -C, --compress      Use compression in server/client protocol.
  -#, --debug[=#]     This is a non-debug version. Catch this and exit.
  --debug-check       This is a non-debug version. Catch this and exit.
  -T, --debug-info    This is a non-debug version. Catch this and exit.
  -D, --database=name Database to use.
  --default-character-set=name 
                      Set the default character set.
  --delimiter=name    Delimiter to be used.
  --enable-cleartext-plugin 
                      Enable/disable the clear text authentication plugin.
  -e, --execute=name  Execute command and quit. (Disables --force and history
                      file.)
  -E, --vertical      Print the output of a query (rows) vertically.
  -f, --force         Continue even if we get an SQL error.
  --histignore=name   A colon-separated list of patterns to keep statements
                      from getting logged into syslog and mysql history.
  -G, --named-commands 
                      Enable named commands. Named commands mean this program's
                      internal commands; see mysql> help . When enabled, the
                      named commands can be used from any line of the query,
                      otherwise only from the first line, before an enter.
                      Disable with --disable-named-commands. This option is
                      disabled by default.
  -i, --ignore-spaces Ignore space after function names.
  --init-command=name SQL Command to execute when connecting to MySQL server.

                      (Defaults to on; use --skip-column-names to disable.)
  -N, --skip-column-names 
                      Don't write column names in results.
  --sigint-ignore     Ignore SIGINT (CTRL-C).
  -o, --one-database  Ignore statements except those that occur while the
                      default database is the one named at the command line.
  --pager[=name]      Pager to use to display results. If you don't supply an
                      option, the default pager is taken from your ENV variable
                      PAGER. Valid pagers are less, more, cat [> filename],
                      etc. See interactive help (\h) also. This option does not
                      work in batch mode. Disable with --disable-pager. This

  -p, --password[=name] 
                      Password to use when connecting to server. If password is
                      not given it's asked from the tty.
  -P, --port=#        Port number to use for connection or 0 for default to, in
                      order of preference, my.cnf, $MYSQL_TCP_PORT,
                      /etc/services, built-in default (3306).
  --prompt=name       Set the mysql prompt to this value.
  --protocol=name     The protocol to use for connection (tcp, socket, pipe,
                      memory).
  -q, --quick         Don't cache result, print it row by row. This may slow
                      down the server if the output is suspended. Doesn't use
                      history file.
  -r, --raw           Write fields without conversion. Used with --batch.
  --reconnect         Reconnect if the connection is lost. Disable with
                      --disable-reconnect. This option is enabled by default.
                      (Defaults to on; use --skip-reconnect to disable.)

  --ssl-mode=name     SSL connection mode.
  --ssl-ca=name       CA file in PEM format.
  --ssl-capath=name   CA directory.
  --ssl-cert=name     X509 cert in PEM format.
  --ssl-cipher=name   SSL cipher to use.

  --ssl-crl=name      Certificate revocation list.
  --ssl-crlpath=name  Certificate revocation list path.
  --tls-version=name  TLS version to use, permitted values are: TLSv1, TLSv1.1,
                      TLSv1.2, TLSv1.3
  --ssl-fips-mode=name 
                      SSL FIPS mode (applies only for OpenSSL); permitted
                      values are: OFF, ON, STRICT
  --tls-ciphersuites=name 
                      TLS v1.3 cipher to use.
  -t, --table         Output in table format.
  --tee=name          Append everything into outfile. See interactive help (\h)
                      also. Does not work in batch mode. Disable with
                      --disable-tee. This option is disabled by default.
  -u, --user=name     User for login if not current user.
  -U, --safe-updates  Only allow UPDATE and DELETE that uses keys.
  -U, --i-am-a-dummy  Synonym for option --safe-updates, -U.
  -v, --verbose       Write more. (-v -v -v gives the table output format).
  -V, --version       Output version information and exit.
  -w, --wait          Wait and retry if connection is down.
  --connect-timeout=# Number of seconds before connection timeout.
  --max-allowed-packet=# 
                      The maximum packet length to send to or receive from
                      server.

  --binary-mode       By default, ASCII '\0' is disallowed and '\r\n' is
                      translated to '\n'. This switch turns off both features,
                      and also turns off parsing of all clientcommands except
                      \C and DELIMITER, in non-interactive mode (for input
                      piped to mysql or loaded using the 'source' command).
                      This is necessary when processing output from mysqlbinlog
                      that may contain blobs.
  --connect-expired-password 
                      Notify the server that this client is prepared to handle
                      expired password sandbox mode.
  --network-namespace=name 
                      Network namespace to use for connection via tcp with a
                      server.

/etc/my.cnf /etc/mysql/my.cnf /my.cnf ~/.my.cnf 
The following groups are read: mysql client
The following options may be given as the first argument:
--print-defaults        Print the program argument list and exit.
--no-defaults           Don't read default options from any option file,
                        except for login file.
--defaults-file=#       Only read default options from the given file #.
--defaults-extra-file=# Read this file after the global files are read.
--defaults-group-suffix=#
                        Also read groups with concat(group, suffix)
--login-path=#          Read this path from the login file.

I mean, instead of creating the new database, I get this mysql help response. Trying to fix this for 5 hours. At first I tried to use -p with password, but mysql gave me a warning that it is unsafe, and I guess that warning is breaking the pipeline. So I found a solution, by adding my credentials to cnf file and specify it by using default-extra-file option. Now file is seems found, but I cant understand why Im getting mysql help instead of command executon. maybe someone can help me?
