Dockerコンテナ内でのviの挙動がおかしい

DockerでシンプルにApacheをインストールしたコンテナを作成しました。

DockerFile
FROM centos

LABEL title="TestApacheImage"\
      version="1.0"\
      description="test apache"

RUN ["rpm", "--import", "/etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7"]
RUN ["yum", "-y", "install","httpd"]

EXPOSE 80

CMD ["/usr/sbin/httpd", "-D", "FOREGROUND"]

これを以下のコマンドで起動します。

#ビルド
docker image build -t apache -f DockerFile .

#run(viで開いたとき変な折り返しをしていたので環境変数いじってます)
docker container run -it -p 8080:80 -e COLUMNS=$COLUMNS -e LINES=$LINES -e TERM=$TERM apach

するとこのようなエラーが出たので

AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 172.17.0.2. Set the 'ServerName' directive globally to suppress this message

ServerNameを編集するために、/etc/httpd/conf/httpd.conf をviで開いてみました。

httpd.conf
#
# This is the main Apache HTTP server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.4/> for detailed information.
# In particular, see
# <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so 'log/access_log'
# with ServerRoot set to '/www' will be interpreted by the
# server as '/www/log/access_log', where as '/log/access_log' will be
# interpreted as '/log/access_log'.

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path.  If you point
# ServerRoot at a non-local disk, be sure to specify a local disk on the
# Mutex directive, if file-based mutexes are used.  If you wish to share the
# same ServerRoot for multiple httpd daemons, you will need to change at
# least PidFile.
#
ServerRoot "/etc/httpd"

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses.
