记录一次构建armv8平台vsftpd Docker镜像的过程

因客户使用飞腾2000平台需要部署vsftpd,但因系统环境不同存在诸多部署问题,且无适配的armv8版本vsftpd容器,特此专门构建vsftpd镜像并记录构建过程

# Run in the foreground to keep the container running:

# Allow anonymous FTP? (Beware - allowed by default if you comment this out).

# Uncomment this to allow local users to log in.
# When SELinux is enforcing check for SE bool ftp_home_dir
local_enable=YES

# Uncomment this to enable any form of FTP write command.
write_enable=YES

# Default umask for local users is 077. You may wish to change this to 022,
# if your users expect that (022 is used by most other ftpd's)
local_umask=022

# Uncomment this to allow the anonymous FTP user to upload files. This only
# has an effect if the above global write enable is activated. Also, you will
# obviously need to create a directory writable by the FTP user.
# When SELinux is enforcing check for SE bool allow_ftpd_anon_write, allow_ftpd_full_access
anon_upload_enable=NO

# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
anon_mkdir_write_enable=NO

# Activate directory messages - messages given to remote users when they
# go into a certain directory.
dirmessage_enable=YES

# Activate logging of uploads/downloads.
xferlog_enable=YES

# Make sure PORT transfer connections originate from port 20 (ftp-data).
connect_from_port_20=YES

# If you want, you can arrange for uploaded anonymous files to be owned by
# a different user. Note! Using "root" for uploaded files is not
# recommended!
chown_uploads=NO
chown_username=root

# This option is the name of the file to which we write the vsftpd style log file.
# This log is only written if the option xferlog_enable is set, and xferlog_std_format is NOT set.
# Alternatively, it is written if you have set the option dual_log_enable.
# One further complication - if you have set syslog_enable, then this file is not written and output is sent to the system log instead.
vsftpd_log_file=/var/log/vsftpd/vsftpd.log

# This option is the name of the file to which we write the wu-ftpd style transfer log.
# The transfer log is only written if the option xferlog_enable is set, along with xferlog_std_format.
# Alternatively, it is written if you have set the option dual_log_enable.
xferlog_file=/var/log/vsftpd/xferlog.log

# If you want, you can have your log file in standard ftpd xferlog format.
# Note that the default log file location is /var/log/xferlog in this case.

# You may change the default value for timing out an idle session.

# You may change the default value for timing out a data connection.

# It is recommended that you define on your system a unique user which the
# ftp server can use as a totally isolated and unprivileged user.
#nopriv_user=ftpsecure

# Enable this and the server will recognise asynchronous ABOR requests. Not
# recommended for security (the code is non-trivial). Not enabling it,
# however, may confuse older FTP clients.
#async_abor_enable=YES

# By default the server will pretend to allow ASCII mode but in fact ignore
# the request. Turn on the below options to have the server actually do ASCII
# mangling on files when in ASCII mode. The vsftpd.conf(5) man page explains
# the behaviour when these options are disabled.
# Beware that on some FTP servers, ASCII support allows a denial of service
# attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
# predicted this attack and has always been safe, reporting the size of the
# raw file.
# ASCII mangling is a horrible feature of the protocol.

# You may specify a file of disallowed anonymous e-mail addresses. Apparently
# useful for combatting certain DoS attacks.
#deny_email_enable=YES
# (default follows)
#banned_email_file=/etc/vsftpd/banned_emails

# You may specify an explicit list of local users to chroot() to their home
# directory. If chroot_local_user is YES, then this list becomes a list of
# users to NOT chroot().
# (Warning! chroot'ing can be very dangerous. If using chroot, make sure that
# the user does not have write access to the top level directory within the
# chroot)
chroot_local_user=YES
#chroot_list_enable=YES
# (default follows)
#chroot_list_file=/etc/vsftpd/chroot_list

# Allow chroot writeable
allow_writeable_chroot=YES

# This option should be the name of a directory which is empty.
# Also, the directory should not be writable by the ftp user.
# This directory is used as a secure chroot() jail at times vsftpd does not require filesystem access.
# Default: /usr/share/empty
secure_chroot_dir=/var/run/vsftpd/empty

# You may activate the "-R" option to the builtin ls. This is disabled by
# default to avoid remote users being able to cause excessive I/O on large
# sites. However, some broken FTP clients such as "ncftp" and "mirror" assume
# the presence of the "-R" option, so there is a strong case for enabling it.
ls_recurse_enable=NO

# When "listen" directive is enabled, vsftpd runs in standalone mode and
# listens on IPv4 sockets. This directive cannot be used in conjunction
# with the listen_ipv6 directive.
listen=YES

# This directive enables listening on IPv6 sockets. By default, listening
# on the IPv6 "any" address (::) will accept connections from both IPv6
# and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6
# sockets. If you want that (perhaps because you want to listen on specific
# addresses) then you must run two copies of vsftpd with two configuration
# files.
# Make sure, that one of the listen options is commented !!
listen_ipv6=NO

pam_service_name=vsftpd
userlist_enable=YES
tcp_wrappers=YES

将以上三个文件放到同一目录中,使用docker build -t hackerbs/vsftpd:latest .构建即可。
